Request direct access button for projects.

Proposal

This feature is to add a button to allow indirect members to request access to groups projects as direct members.

Currently users can request access to internal or public projects as long as they are not members of it. But when a user is has inherited access they are not able to request access any more. This is expected, yet there are certain features, that require direct membership, features like code owners.

Having the option to request direct members would simplify customer workflow
