Extract `meltano permissions` into separate project
meltano permissions is not relevant to our target persona, maintaining, supporting, or improving it is no longer a priority for the Meltano team.
Since it is still a very useful tool that deserves more attention and care than we can give it, and since it does not depend on any other Meltano components or code, it is a perfect candidate for extraction out of our codebase so that another party whose goals are more closely aligned with maintaining this project can maintain it going forward.
Since the GitLab Data Team (specifically, @tayloramurphy) has been its primary (and only?) user, that would be the most natural candidate
