In this changeset, I implemented a background scheduler service for Watcher and more particularly for the Decision Engine where I made it create 2 types of job per cluster data model collector plugin: - An initial job that is asynchronously executed upon starting the Decision Engine - A periodical job that gets triggered every configurable interval of time Change-Id: I3f5442f81933a19565217b894bd86c186e339762 Partially-Implements: bluprint cluster-model-objects-wrapper
