Allow delegation of Maintainer role to non-project leads
The Eclipse Titan project has numerous project leads because that is how they allow committers to have Maintainer permission on GitLab repo. I don't know what it means to be a Maintainer on GitLab repo as opposed to lower level of permissions. However this seems like an issue that could be handled similar to Bugzilla Permission Delegation? Or maybe there are some permissions that are currently too restricted that could be opened to all committers.
Perhaps @lnagy could expand on the permissions that the PLs would want to delegate so that future projects that migrate to GitLab don't have the same issues.
At today's Architecture Council (AC) call @wbeaton recommended filing this bug as a first step. If there are questions to go back to AC let me know and I can try to get the info from the AC.
