Currently clustering steps are very static, if for a reason first node in the inventory fails and gets re-introduced - K-A will create a second empty cluster on that node. This patch changes the approach and checks if cluster exists, if it does - chooses a donor for the new node from currently running node set. Also it fixes node replacement - it removes old node from cluster (that has the same ip address as newly provisioned node). Closes-Bug: #1875223 Change-Id: Ia025283e38ea7c3bd37c7a70d03f6b46c68f4456
