Whilst the `networking-troubleshooting` docs page already mentions that
a direct connection can be established over a private network, even if
there are no STUN servers, it's worth this is the case at the end of the
ping output.
This also removes a print statement that was dirtying up the diagnostic
output, and corrects the name of the `--disable-direct-connections`
flag.
First PR to address #14244.
Adds common potential reasons as to why a direct connection to the workspace agent couldn't be established to `coder ping`:
- If the Coder deployment administrator has blocked direction connections (`CODER_BLOCK_DIRECT`).
- If the client has no STUN servers within it's DERP map.
- If the client or agent appears to be behind a hard NAT, as per Tailscale `netInfo.MappingVariesByDestIP`
Also adds a warning if the client or agent has a network interface below the 'safe' MTU for tailnet. This warning is always displayed at the end of a `coder ping`.
Beginnings of a solution to #12297
Doesn't cover disco or definitively display whether we successfully connected to DERP, but shows some checklist diagnostics for connecting to an agent.
For this first PR, I just added it to `coder ping` to see how we like it, but could be incorporated into `coder ssh` _et al._ after a timeout.

* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: rename startup logs to agent logs
This also adds a `source` property to every agent log. It
should allow us to group logs and display them nicer in
the UI as they stream in.
* Fix migration order
* Fix naming
* Rename the frontend
* Fix tests
* Fix down migration
* Match enums for workspace agent logs
* Fix inserting log source
* Fix migration order
* Fix logs tests
* Fix psql insert
* fix: remove startup logs eof for streaming
We have external utilities like logstream-kube that may send
logs after an agent shuts down unexpectedly to report additional
information. In a recent change we stopped accepting these logs,
which broke these utilities.
In the future we'll rename startup logs to agent logs or something
more generalized so this is less confusing in the future.

* fix: Fix ssh message/spinner in VSCode integrated terminal
The messages never show up in VSCode integrated terminal due to the
defer `fmt.Fprintf`. There could be a race in VSCode in handling the
terminal codes but ultimately, we can simplify our logic by just
stopping the spinner for the duration of the update.
* Avoid race in starting spinner after exit
* 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 changes all "coder workspace *" commands to root.
A few of these were already at the root, like SSH. The
inconsistency made for a confusing experience.
This enables a "kubernetes_pod" to attach multiple agents that
could be for multiple services. Each agent is required to have
a unique name, so SSH syntax is:
`coder ssh <workspace>.<agent>`
A resource can have zero agents too, they aren't required.

It also adds tests to the cliui for build logs!
