Hi Cloud Foundry,

We have a request from an API client that would like for users to be able
to remove themselves from an Organization or Space. This allows
self-service without the app obtaining an admin token to remove the user.

Several restrictions that we might want to incorporate:

- Deny if the user is the last User in the org?
- Deny if the user is the last Org Manager in the org?
- Deny if the user is the last Billing Manager in the org?
- Deny if the user is the last User in the space?
- Deny if the user is the last SpaceManager in the space?


Any objections to this or any other restrictions we should consider?


Thanks,

Nick
