Code Issues Proposed changes

Scheduler managers enhanced

Browse Source 
- scheduler_manager:
  - added support to trusted token and shared quota
  - implemented backfill strategy
- fairshare_manager: various rewrites and fixes
- nova_manager:
  - added support to user-data (metadata)
  - new implementation of getProjectUsage() and getProjectServers()
- quota_manager: added support to shared quota
- queue_manager: few stylistic changes
- command: shell conforming to the OS style
- setup.cfg: entry points updated
- added functional tests
