In T201504: cloudvps: main/eqiad1 keystone merge, there was some code that wasn't retained for some reason I can't remember.
Specifically:
- nova spread check: to check if instances of a project are spread enough
- keystone toke cleanups
- keystone monitoring of projects and users
Shall we reintroduce them?
Note: they have been running because they weren't cleaned up from main when puppet code was removed.
