The periodic jobs are currently getting registered per each worker which means that in cases with large number of workers, the APIs for services such as Heat and Keystone will be hit very hard. This patch resolves this issue by registering the jobs only to the main process, ensuring that they run once per instance (or group of workers). Closes-Bug: #1702349 Change-Id: If9e13effc14fd35e646d02bb4f568e79786aa958
