Handle cinder volume type for multiple cinder stores

Browse Source 
1. Adding 'cinder_volume_type' configuration parameter to allow
cinder stores to specify a volume type for each cinder store.

2. Removed the restrictions are imposed to allow only a single
   instance of the 'cinder'.

Partially Implements: blueprint multiple-cinder-backend-support
