[Feature Request] UI for adding maintainers

[scopatz]

The idea here is simple, but I have no clue how hard it would be to implement. That said, it would be great if warehouse had a user interface for current maintainers of a project to add other maintainers.

As this is a new feature, I'm going to move this out of the 'shutdown' milestone and label it with post launch high priority.

This isn't a new feature, it exists on PyPI today, people can add/remove Owners and Maintainers and it's needed before we shut down legacy or else people won't be able to manage the permissions of their projects.

In our meeting today we decided this belongs in the first milestone, the MVP for package maintainers.
