Thomas Eizinger e901d51550 refactor(gateway): split proxy IP assignment from authorisation (#6812 )

At the moment, the mapping of proxy IPs to the resolved IPs of a DNS
resource happens at the same time as the "authorisation" that the client
is allowed to talk to that resource. This is somewhat convoluted
because:

- Mapping proxy IPs to resolved IPs only needs to happen for DNS
resources, yet it is called for all resources (and internally skipped).
- Wildcard DNS resources only need to be authorised once, after which
the client is allowed to communicate with any domain matching the
wildcard address.
- The code that models resources within `ClientOnGateway` doesn't
differentiate between resource types at all.

With #6461, the authorisation of a resource will be completely decoupled
from the domain resolution for a particular domain of a DNS resource. To
make that easier to implement, we re-model the internals of
`ClientOnGateway` to differentiate the various resource types. Instead
of holding a single vec of addresses, the IPs are now indexed by the
respective domain. For CIDR resources, we only hold a single address
anyway and for the Internet Resource, the IP networks are static.

This new model now implies that allowing a resource that has already
been allowed essentially implies an update and the filters get
re-calculated.

gateway

This crate houses the Firezone gateway.

Building

You can build the gateway using: cargo build --release --bin firezone-gateway

You should then find a binary in target/release/firezone-gateway.

Running

The Firezone Gateway supports Linux only. To run the Gateway binary on your Linux host:

Generate a new Gateway token from the "Gateways" section of the admin portal and save it in your secrets manager.
Ensure the FIREZONE_TOKEN=<gateway_token> environment variable is set securely in your Gateway's shell environment. The Gateway requires this variable at startup.
Set FIREZONE_ID to a unique string to identify this gateway in the portal, e.g. export FIREZONE_ID=$(uuidgen). The Gateway requires this variable at startup.
Now, you can start the Gateway with:

firezone-gateway

If you're running as a non-root user, you'll need the CAP_NET_ADMIN capability to open /dev/net/tun. You can add this to the gateway binary with:

sudo setcap 'cap_net_admin+eip' /path/to/firezone-gateway

Ports

The gateway requires no open ports. Connections automatically traverse NAT with STUN/TURN via the relay.
