Lance Bragstad 88b993b192 Implement project personas for snapshot metadata
This commit updates the policies to use the default roles provided by
keystone allowing for a more consistent authorization experience across
OpenStack services. This commit also includes read-only support for read
APIs.

Also removes the following from tests/unit/policy.yaml:
-"volume:get_snapshot_metadata": ""
-"volume:update_snapshot_metadata": ""
-"volume:delete_snapshot_metadata": ""
