Refresh quotas usage

Registered by Romain Hardouin on 2015-03-05

For some reasons*, the quotas usage can be out of sync.
When a quota is wrongfully reached, a user cannot launch new VMs anymore.
This "refresh" feature allows operators to quickly unblock users without
manually running queries against the database or temporarily increase the
quota.

[*] It seems that there are several root causes and there is no procedure
     to reproduce bugs. Although these root causes will eventually be
     identified, we cannot guarantee that some bugs will not occur again.
