Services running on master are using RemoteAuthorizationEnforcer, which should use DefaultAuthorizationEnforcer.
Steps to reproduce:
1. In cdap cli, log in as super user,
2. create a namespace
3. grant action READ/WRITE/ADMIN/EXECUTE on the namespace to user alice.
4. Changing user to alice and listing the namespaces does not return the namespace. The grant action does not take effect at once, still need to wait for the cache timeout.
