fixes#16828
With all the recent changes, I believe it is now safe to change the Call to Action for `config-ssh` to use the hostname suffix rather than prefix if it was set.
relates to #16828
Changes SSH config so that suffixes only match if Coder Connect is not running / available. This means that we will use the existing Coder Connect tunnel if it is available, rather than creating a new tunnel via `coder ssh --stdio`.
Adds a new hidden subcommand `coder connect exists <hostname>` that checks if the name exists via Coder Connect. This will be used in SSH config to match only if Coder Connect is unavailable for the hostname in question, so that the SSH client will directly dial the workspace over an existing Coder Connect tunnel.
Also refactors the way we inject a test DNS resolver into the lookup functions so that we can test from outside the `workspacesdk` package.
Wires up `config-ssh` command to use a hostname suffix if configured.
part of: #16828
e.g. `coder config-ssh --hostname-suffix spiketest` gives:
```
# ------------START-CODER-----------
# This section is managed by coder. DO NOT EDIT.
#
# You should not hand-edit this section unless you are removing it, all
# changes will be lost when running "coder config-ssh".
#
# Last config-ssh options:
# :hostname-suffix=spiketest
#
Host coder.* *.spiketest
ConnectTimeout=0
StrictHostKeyChecking=no
UserKnownHostsFile=/dev/null
LogLevel ERROR
ProxyCommand /home/coder/repos/coder/build/coder_config_ssh --global-config /home/coder/.config/coderv2 ssh --stdio --ssh-host-prefix coder. --hostname-suffix spiketest %h
# ------------END-CODER------------
```
Adds `hostname-suffix` as a Config SSH option that we get from Coderd, and also accept via a CLI flag.
It doesn't actually do anything with this value --- that's for PRs up the stack, since we need the `coder ssh` command to be updated to understand the suffix first.

The experimental functions in `golang.org/x/exp/slices` are now
available in the standard library since Go 1.21.

Rather than create a separate `Host` entry for every workspace,
configure a wildcard such as `coder.*` which can accomodate all of a
user's workspaces.
Depends on #16088.
* 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
* feat: Use Tailscale networking by default
Removal of WebRTC code will happen in another PR, but it
felt dangerious to default and remove in a single commit.
Ideally, we can release this version and collect final
thoughts and feedback before a full commitment.
* Remove UNIX forwarding
Tailscale doesn't support this, and adding support
for it shouldn't block our rollout. Customers can
always forward over SSH.
* Update cli/portforward_test.go

* fix: Use smarter quoting for ProxyCommand in config-ssh
This change takes better into account how OpenSSH executes
`ProxyCommand`s and applies quoting accordingly.
This supercedes #3664, which was reverted.
Fixes#2853
* fix: Ensure `~/.ssh` directory exists
* feat: Rename config-ssh `--diff` to `--dry-run`
Since the intent between diff and dry-run are different, this change
allows for interactive prompts to be shown during `--dry-run`,
previously prompts were disabled. Dry-run can also be chanied with
`--yes` and `--use-previous-options` for non-interactive modes.
Dry-run is like a normal run with changes replaced by diff.
Fixes#2530

- Magic block is replaced by Include statement
- Writes are only done on changes
- Inform user of changes via prompt
- Allow displaying changes via `--diff`
- Remove magic block if present
- Safer config writing via tmp-file + rename
- Parse previous `config-ssh` options, compare to new options and ask to use new (otherwise old ones are used)
- Tests the new functionality
Fixes#1326
* fix: Remove unused workspace routes in favor of list with filter
This consolidates the workspace routes into a single place.
It allows users to fetch a workspace by their username and
workspace name, which will be used by the frontend for routing.
* Fix RBAC
* Fix CLI usages
* feat: Add SSH agent forwarding support to coder agent
* feat: Add forward agent flag to `coder ssh`
* refactor: Share setup between SSH tests, sync goroutines
* feat: Add test for `coder ssh --forward-agent`
* fix: Fix test flakes and implement Deans suggestion for helpers
* fix: Add example to config-ssh
* fix: Allow forwarding agent via -A
