feat(cli): add logs cmd (#21430)

This PR adds a command to view the provisioner and agent logs for a
given workspace.
Note: I did investigate using the existing `cliui` methods to tail the
logs but they are tailored to a very specific use-case.

Other changes:
- Adds `Agents` to `dbfake.WorkspaceResponse`
- Adds methods to generate provisioner and agent logs in `dbgen`
