[Michael Dovgal <1703584@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

During executing tenant_limit_usages quotas function here [0] we get
information about cinder volumes/snapshots/gigabites usage. Like this:

{u'maxTotalBackupGigabytes': 1000,
 u'maxTotalBackups': 10,
 u'maxTotalSnapshots': 10,
 u'maxTotalVolumeGigabytes': 1000,
 u'maxTotalVolumes': 10,
 u'totalBackupGigabytesUsed': 1,
 u'totalBackupsUsed': 1,
 u'totalGigabytesUsed': 8,
 u'totalSnapshotsUsed': 1,
 u'totalVolumesUsed': 6
}

After it here [1] we trying to get the same information as we've already got and add it one more time to limits dict here [2]
Also these calls slows down the application, so we need to get rid of them.
