⭐ support terraform discovery over gitlab
```bash cnquery run gitlab --group mondoolabs --project example-gitlab --discover terraform -c 'terraform.blocks' ``` Unlike v8, this also cleans up the temporary git repos on provider shutdown. Follow-up: We have a general issue that calls connect twice on all providers right now, leading to double-clones of the git repo. This will be solved via connection re-use.
