Leave project features #1542
Description
Background
Users can request to join a project but there's no defined workflow for a user to leave a project in DEEP. Allowing users to leave a project helps users better organize active ongoing projects.
Acceptance Criteria
- All members of a project should see a 'Leave project' button in a project item in 'Home' page.
- If an admin attempts to leave a project, it should not be allowed. Instead, the user should be prompted with a message to handover the admin rights of a project to someone else and then try leaving the project
