Adds default values for policy rules in code and removes
them from etc/policy.json file. The change is validated
by the nova.tests.unit.test_policy unit tests.
Adds default policy rules in policy_fixture. The policy_fixture
is currently loading an incomplete set of policy rules (from
policy.json or fake_policy), resulting in unit tests running
with an incomplete set of policy rules.
