cloud_tenant_mapping not set for storage sub-providers

Cinder and Swift Managers do not have cloud_tenant_mapping set.
The OpenStack CloudManager now sets each storage provider's
cloud_tenant_mapping whenever there is an update.

This is required because CloudTenancyMixin checks the storage
provider's cloud_tenant_mapping value, and not the cloud
provider's value.
