RemoteRepositoryConfigType defines how a remote repository is configured and
managed. Currently only "remotesource" is supported.
In future other config types (like a fully manual config) could be supported.
In future we may support specifying a remote source for a project without a
linked account and thus use a user provided token (saved in the project) or
other ways to define a remote repo (like standard git repos over ssh).
Additionally don't save a CloneURL field inside the project type.
If in future some git source doesn't provide a clone url we could just calculate
it from project.RepoPath or call the remote api to retrieve it.
