The default rule is broken in the current implementation of
ceilometer rbac, because ceilometer rbac.py does not leverage
the support provided by oslo_policy . It instead tries to
loop through all the rules in the policy.json to check if the
rule corresponding to the requested REST api matches with the
any in the policy.json. In this process, it completely ignores
the existence of the default rule.
