> When a service is disabled, the plugins should be refreshed with empty policy list - as if no policy exists in the service. In this case, the components like HDFS and YARN will enforce component ACLs (since fallback is set to true by default); other components will deny any access - since there is no policy exists to allow any access. And when the service is enabled, the plugins should be refreshed with the policies in the service. To achieve this:
>  - the policyVersion associated with the service should be incremented whenever the service is enabled or disabled. So that the next policy refresh call will send updated policy list
>  - the policy refresh implementation should return empty policy list when service is disabled
