Annoyingly, prometheus Registry collects metrics async, which is causing our test to be racy. They also don't export enough from the Metric interface for us to replicate a synchronous collect, so we have to use Eventually to test.
Adds prometheus metrics to PGPubsub for monitoring its health and performance in production.

Since we run yamux over the websocket, we don't need to ping at the websocket layer because yamux has a 30 second keepalive mechanism enabled in the default config.
The RPC() function isn't called, since Listen() was modified to do this job.
Listen() has the right signature, since it returns a drpc.Conn, rather than the Agent API. That's because tailnet v2 and agent v2 are separate APIs served over the same connection.
It might be clearer to rename `Listen()` to `RPC()` but I'll save that for a different PR.
Adds a new statsReporter subcomponent of the agent, which in a later PR will be used to report stats over the v2 API.
Refactors the logic a bit so that we can handle starting and stopping stats reporting if the agent API connection drops and reconnects.
Moves monitoring of the agent v2 API connection to the yamux layer.
Present behavior monitors this at the websocket layer, and closes the websocket on completion. This can cause yamux to hit unexpected errors since the connection is closed underneath it.
This might be the cause of yamux errors that some customers are seeing
In any case, it's more graceful to close yamux first and let yamux close the underlying websocket. That should limit yamux error logging to truly unexpected/error cases.
The only downside is that the yamux `Close()` doesn't accept a reason, so if the agent becomes outdated and we close the API connection, the agent just sees the connection close without a reason. I'm not sure we log this at the agent anyway, but it would be nice. I think more accurate logging on Coderd are more important.
I've also added some logging when the monitor disconnects for reasons other than the context being canceled (e.g. agent outdated, failed pings).

This PR solves #10478 by auto-filling previously used template values in create and update workspace flows.
I decided against explicit user values in settings for these reasons:
* Autofill is far easier to implement
* Users benefit from autofill _by default_ — we don't need to teach them new concepts
* If we decide that autofill creates more harm than good, we can remove it without breaking compatibility
Fixes an issue where a MultiAgentConn isn't closed properly when the coordinator it is connected to is closed.
Since servertailnet checks whether the conn is closed before reinitializing, it is important that we check this, otherwise servertailnet can get stuck if the coordinator closes (e.g. when we switch from AGPL to PGCoordinator after decoding a license).
We're failing tests on error logs like this: https://github.com/coder/coder/actions/runs/7706053882/job/21000984583
Unfortunately, the error we hit, when the underlying connection is closed, is unexported, so we can't specifically ignore it.
Part of the issue is that agent.Close() doesn't wait for these goroutines to complete before returning, so the test harness proceeds to close the connection. This looks to our product code like the network connection failing. It would be possible to fix this, but just doesn't seem worth it for the extra insurance of catching other error logs in these tests.
Adds logging to yamux when used for tailnet client connections, e.g. CLI and wsproxy. This could be useful for debugging connection issues with tailnet v2 API.
`agentsdk` depends on `agent/proto` because it needs to get the version to dial.
Therefore, the conversion routines need to live in `agentsdk` so that we can convert to and from the Manifest.
I briefly considered refactoring the agent to only reference `proto.Manifest`, but decided against it because we might have multiple protocol versions in the future, its useful to have a protocol-independent data structure.
Fixes#8218
Removes `wsconncache` and related "is legacy?" functions and API calls that were used by it.
The only leftover is that Agents still use the legacy IP, so that back level clients or workspace proxies can dial them correctly.
We should eventually remove this: #11819
