This change set implements support for the `--deploy-token-auth` option
in the `flux bootstrap gitlab` command.
That option will reconcile a GitLab Project Deploy Token to use for the
authentication of the GitLab git repository.
A GitLab Project Deploy Token can be used the same way as a Personal
Access Token which is already supported via `--token-auth`.
The difference with the GitLab Project Deploy Token is that the token is
managed (created, updated, deleted) by Flux and not provided by the
user.
This change is transparent to the source-controller.
A prerequisite for this change is the
`fluxcd/go-git-providers` change here:
