Subject: [PATCH] Implement `add` and `delete` sub-commands to `wvd`

This pull request adds the features that are detailed in this issue:
https://github.com/devine-dl/devine/issues/2

Also changes some debug logs to info logs, as the information would generally be wanted. Also changes some logging logs to console.logs.
