Code Issues Proposed changes

Use elevated context to query DB in VolumeNumberWeigher

Browse Source 
Currently tenant would fail to create volume, if cinder uses
VolumeNumberWeigher.

This will elevate tenant to admin privilege, then VolumeNumberWeigher
has the privilege to get volume count of each hosts.
