Part of a small yak shave for #3817
The `atomicwrites` lib uses the atomic rename trick and does correct
fsyncs for us, so if we lose power while rewriting or reverting
`/etc/resolv.conf`, it should always be in a recoverable state. (Unless
the hard drive lies about fsync, but then it's beyond our control.)

The reference that is specified as part of the connection intent
fulfills one particular purpose: To avoid accepting connection details
for a "stale" intent, i.e. a previous one that we sent for the same
resource.
With the move to `phoenix-channel` in #3682, we can no longer specify
the reference explicitly. Instead, sending a message to the portal gives
us an `OutboundRequestId`.
To make the transition in #3682 easier, we emulate this behaviour here
temporarily in the `ControlPlane` of the clients.
This PR doesn't yet provide support for the update of upstream DNS but
it does provide support for all the other resources update messages.
Should comply with the description of issue #2022 but it doesn't respond
to DNS upstream updates which is imply it should on the issue title

It is still client-specific, but this was the closest place I could find
in connlib to put it.
A hypothetical GUI / .deb / systemd-involved gateway would need to be
"dev.firezone.gateway"
Extracted out of #3391.
We don't actually need this for #3391 though because we've added a
compatibility layer during deserialization. But, it will be good to
remove that compat layer at some point which means we have to return the
addresses as plain socket addresses. Because that is a breaking change,
I decided to extract this into a different PR.

If `FIREZONE_DNS_CONTROL` is set to `systemd-resolved`, then shell out
to `resolvectl` to request all system DNS queries to go to Firezone's
sentinel DNS server(s).

Reverts #3622 I don't know why, but that change seemed to cause the
`/etc/resolv.conf` test to fail in CI and I was thinking of the "roll
back first" principle
https://cloud.google.com/blog/products/gcp/reliable-releases-and-rollbacks-cre-life-lessons
~~I also change one `ping` in CI to `until ping`. This was an earlier
attempt before I did the revert, and it seems safe to leave it in.~~
With #3391, constructing a new tunnel will no longer be `async` which
makes DNS resolution the only `async` component of
`set_peer_connection_request`. In general, adding resources as part of
setting up a connection is a duplicated of the logic within
`allow_access`.
We solve both of these problems at once by moving the DNS resolution out
of `connlib` into the `gateway` binary and perform it as part of the
eventloop during a connection setup.
Only user-facing if users are using the Docker image for the Linux
client.
I split off a module for `/etc/resolv.conf` since the code and unit
tests are about 300 lines and aren't related to the rest of the
`tun_linux.rs` code.

The Docker image for the client is opted in to this new feature. The
bare `linux-client-x64` exe is not. I don't know if users are using the
Docker images?
I wanted to use CLI args, but the DNS control code ("config" or
"control"? Or "SplitDNS"?) has to run at the end of `set_iface_config`,
which on Linux runs in a worker, so I couldn't figure out how to move it
into `on_set_interface_config` in the callbacks. Maybe there is a way,
but the env var results in a small diff.
This splits off the easy parts from #3605.
- Add quotes around `PHOENIX_SECURE_COOKIES` because my local
`docker-compose` considers unquoted 'false' to be a schema error - Env
vars are strings or numbers, not bools, it says
- Create `test.httpbin.docker.local` container in a new subnet so it can
be used as a DNS resource without the existing CIDR resource picking it
up
- Add resources and policies to `seeds.exs` per #3342
- Fix warning about `CONNLIB_LOG_UPLOAD_INTERVAL_SECS` not being set
- Add `resolv-conf` dep and unit tests to `firezone-tunnel` and
`firezone-linux-client`
- Impl `on_disconnect` in the Linux client with `tracing::error!`
- Add comments
```[tasklist]
- [x] (failed) Confirm that the client container actually does stop faster this way
- [x] Wait for tests to pass
- [x] Mark as ready for review
```
Currently, we log messages from the portal several times via different
ways. For one, the message is included in the span via
`tracing::instrument`. Then it is also logged on `trace!` level twice
(this PR removes one of them). Plus, the fields of the
`request_connection` span are not printed in a very human-readable way
(bytes arrays). This makes the logs super noisy, see here for the latest
run on `main`:
https://github.com/firezone/firezone/actions/runs/7808301643/job/21298585685#step:13:13
Compare this with the logs from the run in this PR:
https://github.com/firezone/firezone/actions/runs/7813774334/job/21313812863?pr=3596#step:13:13
Some of these improvements were made as part of debugging #3391.
Extracting them here in a separate PR to reduce the diff of #3391.

Closes#3217. I just now noticed that one was assigned to me

The sorting is naive, just sorts the UTF-8 encoded bytes, so lowercase
resources come after all uppercase resources, and it's probably very
wrong for anything outside Latin-1 and English locale. If the names are
identical, resource ID tie-breaks.
This required making `allow_access` `async` which is ugly, but we can
fix it later like we did it with `set_peer_connection_request`, but
doing this ASAP otherwise this would block the `peers_by_ip` struct and
also block the executor a bunch of times and slow everything down.

While working on #3288 I saw a few messages that we don't explicitly
handle from the portal.
This PR changes it so that we handle them correctly and we don't just
depend on coincidental behavior..
Some dns servers return NXDOMAIN for queries where the address exists
but there is no
answer for the given query type(e.g. AAAA-only records). This is not up
to spec and
musl PROPERLY assumes that means there is no record of any type. Saddly,
this happens even
with google DNS so we can expect it to happen everywhere. So we use
getaddrinfo to separate
requests for A and AAAA queries and preventing this.
Seems to work locally, though the exact situation where we have a record
that returns NXDOMAIN while it exists is easier to reproduce in staging,
we should test it after we merge.

Also refactored to extract an auth state machine. The auth logic
previously was scattered throughout the GUI module, which would make it
hard to audit. Because of the refactoring I was able to add some simple
unit tests.
... and move its methods into ResourceDescription.
This was a TODO from some pull request in the last few days. I assume
the goal is to share this function between all clients if needed. It
doesn't reduce the number of lines of code, since I could have removed
ResourceDisplay and done this on-the-fly when building the systray menu,
as an alternative.
Fixes#2470, now for linux it looks like:
```
Alpine Linux/3.19.0 (x86_64;5.15.133.1-microsoft-standard-WSL2;) connlib/1.0.0
```
For macos it looks like:
```
Mac OS/13.4.1 (arm64;22.5.0;) connlib/1.0.0
```
and this is how it looks on android:
```
Android/Unknown 6.1.23-android14-4-00257-g7e35917775b8-ab9964412 connlib/1.0.0
```
note: seems like in android emulator at least we can't get the
architecture so easily
Should fix#2880
The way I do it is after ~10 seconds dropping the
`gateway_awaiting_connection` and let the client try the connection
again, depending on upper layer, I think this is fine since the cases
where this happens is unlikely.
It's hard to test thoroughly but I'll test with bad-condition
simulators, [pumba](https://github.com/alexei-led/pumba) seems
promising. In the meantime I'm still creating the PR so that I can have
it reviewed.
Edit: Using Pumba with different % of packet loss things seems to go
well, and connections are actually established even if the packets are
loss. (Making a note that we should integrate pumba with our CI)
Fixes#2948
So it seems that it's easiest just to use an old-fashioned semver
string. This means we'll need to keep a version matrix in the docs of
which components are supported and for how long, but it's better than
having different version schemes for different Firezone components
altogether.

Found a reliable way to return default system DNS resolvers on iOS and
macOS. Even if this method is not perfect, I think it's still worth
pursuing because:
* Many administrators will set an upstream resolver in the portal anyway
(bypassing client system resolvers)
* It unifies our Split DNS approach across platforms (assuming we can
query the default system resolvers on Windows), allowing connlib to
intercept all DNS queries on all platforms. This opens the door for some
interesting feature possibilities in the area of malicious query
blocking. This also makes DNS bugs easier to investigate because there's
only one codepath for packets to take. See
https://github.com/firezone/firezone/issues/2859
Draft because it needs more testing and I need to figure out the
`RustVec<RustString>` type for the Swift -> Rust FFI.
Refs #2713
Previously, we just expected the portal to disconnects us and 401 on the
retry, right now we harden that behaviour by also just disconnecting
when token expiration.
This seems to work, there's another part to this which is not only
handling the replies but also handling the message generated by the
portal, I'll implement that when I can easily test expirying tokens, for
now this makes the client much more stable.
Fixes: #2854.
Note: this is ready for review but reproducing the bug that triggered
the fix takes ~1 hour or so, so I would like to wait to check that's
fixed.
Can be reviewed meanwhile.
This PR changes the protocol and adds support for DNS subdomains, now
when a DNS resource is added all its subdomains are automatically
tunneled too. Later we will add support for `*.domain` or `?.domain` but
currently there is an Apple split tunnel implementation limitation which
is too labor-intensive to fix right away.
Fixes#2661
