Boaz Leskes 318a4e3ef6 Introduce dedicated master nodes in testing infrastructure (#18514) ... This PR changes the InternalTestCluster to support dedicated master nodes. The creation of dedicated master nodes can be controlled using a new `supportsMasterNodes` parameter to the ClusterScope annotation. If set to true (the default), dedicated master nodes will randomly be used. If set to false, no master nodes will be created and data nodes will also be allowed to become masters. If active, test runs will either have 1 or 3 masternodes		2016-05-27 08:44:20 +02:00
