> OozieWorkflowEngine.getCoordActions() gets instances by calling oozieclient.getCoordAction()
for each action. Its not efficient to call oozie API for each instance. Instead, doSummaryJobAction()
gets all instances in bulk using oozieclient.getCoordJobInfo(). But this uses offset which
won't work with purging of coord actions. A new API was added in oozie to get coord actions
between timestamps. We should use that for both usecases
