ranger.plugin.hawq.policy.pollIntervalMs is a real property used by the
service and determines the frequency of policy refreshes performed by Ranger
Plugin.
policy.wait.interval.ms is the property used only by integration test suite
to wait between updating policy in Ranger and trying to evaluate the request.
In our tests we currently set wait.interval = 3 * pollInterval, even that
sometimes causes random test failures when the system is under heavy load. We
can optimize this further, if needed.
