Add support for Oslo Policies to Trove

The Oslo Policy library provides support for RBAC policy
enforcement across all OpenStack services.

Update the devstack plugin to copy the default policy file
over to /etc/trove in the gate environments.

Note: Not adding a rule for 'reset-password' instance
action as that API was discontinued years ago
and is now just waiting for removal (Bug: 1645866).
