Sabari Kumar Murugesan aa10f66ee0 VMware: Support Multiple Datastores
Support for VMware store to use multiple datastore backends.

Spec (approved):
https://review.openstack.org/#/c/146723/

tl;dr:
1. Adds a new config option vmware_datastores to configure
   multiple datastores.
2. Implements a selection logic based on priority to choose
   from the list of datastores.
3. Modifies StoreLocation parsing logic to identify datastore
   related info from location URI.
