----------------------------------------

             Summary: Addable and deletable components should be derived from cardinality
field 
                 Key: AMBARI-6677
                 URL: https://issues.apache.org/jira/browse/AMBARI-6677
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.7.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
             Fix For: 1.7.0


Currently, StackServiceComponent model hard-codes the list of service components that can
be added or deleted to a host.

Instead of maintaining a list, we should derive the logic for allowing addition or deletion
of a host component via cardinality field.

For deletable master components, Let zookeeper server be the only component that can be deleted.
