Slave components in decommission state restart during corresponding Service restarts, but they should not

Slave components in decommission state restart with other service components during Service Restart operation, but it should not.

STR:
1) Deploy cluster by default
2) Turn any slave component to Decommission state (e.g. Datanode)
3) Go to Services page and Restart corresponding service (HDFS)

Expected result: Datanode in Decommission state should not restart with other HDFS components

Actual result: Datanode in Decommission state restarts with other HDFS components
