Update compute hypervisor tests to adopt new policies

Nova is moving to new policy defaults in ussuri[1] where
few polciies are made more granular to adopt the new defaults.

With granularity in few policies make change in policy name so
we have update the patrole tests to start checking against the
new policy names from ussuri onwards.

This commit updates the hypervisors policy tests
to move to new policies from ussuri onwards.
