* fix: Improve tailnet connections by reducing timeouts
This awaits connection ping before running a dial. Before,
we were hitting the TCP retransmission and handshake timeouts,
which could intermittently add 1 or 5 seconds to a connection
being initialized.
* Update Tailscale
The connection limit wasn't being applied to pubsub, which would
overload the server if a ton of logs were being published at once.
This should fix it, and improve scale a lot!
* feat: Add connection_timeout and troubleshooting_url to agent
This commit adds the connection timeout and troubleshooting url fields
to coder agents.
If an initial connection cannot be established within connection timeout
seconds, then the agent status will be marked as `"timeout"`.
The troubleshooting URL will be present, if configured in the Terraform
template, it can be presented to the user when the agent state is either
`"timeout"` or `"disconnected"`.
Fixes#4678
This feature is used by the coder agent to exchange a new token. By
protecting the SessionToken via mutex we ensure there are no data races
when accessing it.

* chore: Separate the provisionerd server into it's own package
This code should be thoroughly tested now that we understand the abstraction.
I separated it to make our lives a bit easier for external provisioner daemons
as well!
* Add tests
* Add workspace builds
* Add test for workspace resources
* feat: Make workspace watching realtime instead of polling
This was leading to performance issues on the frontend, where
the page should only be rendered if changes occur. While this
could be changed on the frontend, it was always the intention
to make this socket ~realtime anyways.
* Fix workspace tests waiting, erroring on workspace update, and add comments to workspace events
* feat: Add bufferring to provisioner job logs
This should improve overall build performance, and especially under load.
It removes the old `id` column on the `provisioner_job_logs` table
and replaces it with an auto-incrementing big integer to preserve order.
Funny enough, we never had to care about order before because inserts
would at minimum be 1ms different. Now they aren't, so the order needs
to be preserved.
* Fix log bufferring
* Fix frontend log streaming
* Fix JS test
The goroutine launched by `ServerSentEventSender` can perform a write
and flush after the calling http handler has exited, at this point the
resources (e.g. `http.ResponseWriter`) are no longer safe to use.
To work around this issue, heartbeats and sending events are now handled
by the goroutine which signals its closure via a channel. This allows
the calling handler to ensure it is kept alive until it's safe to exit.
