This adds a job that will query the Elasticsearch HTTP cat API to determine whether the desired number of nodes have been discovered via the Zen discovery mechanism to be included in the cluster. This aims to address issues seen when upgrading Elasticsearch, where the snapshot repository job may trigger due to endpoints from older pods being present. This new job will be the dependency required by the snapshot repository job to ensure the ES cluster has the desired number of nodes before attempting to register a snapshot repository or interact with the cluster Change-Id: I94fbbfdec7ca66d04acca9558e56dca3b2bc7d52
