Modify the podManagementPolicy for elasticsearch pods
to OrderedReady so no outage is incurred during application-updates.
This setting will also affect initial application-apply, so the elasticsearch
helm chart is also modified to set the initial_master_nodes to
just the first master pod so it will go ready and the apply can proceed.
