Action other than delete

[tegarimansyah]

Is your feature request related to a problem? Please describe.
Currently, we only have a "delete" action, but I also need to archive, toggle private and public, and remove myself from someone else repo.

Describe the solution you'd like
First, the "delete" button should be changed to drop down with multiple actions. After that, we can use update repository and remove collaborator endpoint:

• archive => "archived" (boolean) attribute
• toggle => "private" (boolean) attribute
• remove from repo => use our own username as a parameter for the group
