Thomas Eizinger a109c1a2ef feat(connlib): discard intermediate resource and TUN updates (#10223)
Right now, the Client event-loops have a channel with 1000 items for
sending new resource lists and updates to the TUN device to the host
app. This is kind of unnecessary as we always only care about the last
version of these. Intermediate updates that the host app doesn't process
are effectively irrelevant.

We've had an issue before where a bug in the portal caused us to receive
many updates to resources which ended up crashing Client apps because
this channel filled up.

To be more resilient on this front, we refactor the Client event loop to
use a `watch` channel for this. Watch channels only retain the last
value that got sent into them.
