[Epic] User deactivation

[xcoulon]

Provide a new /api/namedusers/:username/deactivate endpoint to:

• [x] https://github.com/fabric8-services/fabric8-auth/issues/775 obfuscate and deactivate the account in auth service
• [x] https://github.com/fabric8-services/fabric8-auth/issues/776 revoke all tokens
• [x] https://github.com/fabric8-services/fabric8-auth/issues/777 call other services to deactivate the account
• [x] https://github.com/fabric8-services/fabric8-auth/issues/778 soft-delete the account
• [x] https://github.com/fabric8-services/fabric8-auth/issues/783 unlink the external accounts (GitHub, etc.)
• [x] https://github.com/fabric8-services/fabric8-auth/issues/780 expose endpoint (once everything else above is done, since we don't want to expose an incomplete feature)
• [x] https://github.com/fabric8-services/fabric8-auth/issues/796 track user activity based on token validation and renewal
• [x] https://github.com/fabric8-services/fabric8-auth/issues/791 expose endpoint to list the users to deactivate

• unlink the external accounts? (GitHub, etc.)

Good point. Yes!

We also need to make sure that we log all deprovisioned users.

There is one subtask is missing. Before we expose the endpoint we have to change the registration endpoint. It should handle the situation when we get a request to register a new user who was previously deactivated/soft-deleted.

[alexeykazakov]

Never mind. With data obfuscation we don't have to do extra in the registration flow :)

This Epic (provide /api/namedusers/:username/deactivate endpoint) is done. Closing it.

reopening as I realized that https://github.com/fabric8-services/fabric8-auth/issues/777 was incomplete (missing calls to Che, Jenkins and Env services).
