Other connected clients will now print:
```
Connected to an existing tunnel process running on this machine. You can press:
- Ctrl+C to detach
- "x" to stop the tunnel and exit
- "r" to restart the tunnel
```
These are then sent to the server to have that take effect. This is
mostly some refactors in the singleton_server to make the lifecycle work.
Fixes#167708 by using a more predictable naming scheme.

The VS Code CLI gets run from a bash/shell script. This prevents interactions--in the former case, it doesn't look like a tty, and in the latter case batch scripts don't seem to support having interactive subprocesses.
This PR avoids interactions if stdin is not a tty, prompting the user to use the flag instead. Use of the flag is also persisted like an interactive agreement prompt.
This uses a hash of the tunnel ID to create the connection token, which
should be sufficient to resolve the issues.
We also now publish the protocol version in the tunnel tags, since the
connection token must be supplied in the resolver, which is before we
start connecting to the tunnel.

If a new tunnel `--name` was provided but the existing tunnel was deleted,
the CLI would error out with a lookup failed message. Instead it now
recreates it like it normally would.
