Refactors SSH tests to skip provisionerd and instead use dbfake to insert workspaces and builds. This should make tests faster and more reliable.
dbfake.WorkspaceBuild is refactored to use a "builder" pattern with "fluent" options, as the number of options and variants was starting to get out of hand.
* Adds agenttest.New() helper function
* Makes sure agent gets closed on test cleanup
* Makes sure you don't forget to set session token
* Sets the agent and client logger automatically
* 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
