Review request for Ambari and Alejandro Fernandez.


Bugs: AMBARI-13406
    https://issues.apache.org/jira/browse/AMBARI-13406


Repository: ambari


Description
-------

```
2015-10-13 17:22:13,946 ERROR [qtp-client-87 - /api/v1/clusters/c1/upgrades] handlers.BaseManagementHandler
(CreateHandler.java:persist(65)) - Caught a runtime exception while attempting to create a
resource
java.lang.ClassCastException: org.apache.ambari.server.state.stack.upgrade.RestartGrouping
cannot be cast to org.apache.ambari.server.state.stack.upgrade.Task
	at org.apache.ambari.server.state.stack.upgrade.Grouping$DefaultBuilder.add(Grouping.java:111)
```

Caused by a grouping being bound to task. We need to change:
        <upgrade>
          <task xsi:type="restart" />
        </upgrade>
to
        <upgrade>
          <task xsi:type="restart-task" />
        </upgrade>

Testing
-------

Performed a rolling upgrade of a ZK cluster. Running through tests now as well (actually,
mostly looking for disabled tests that can be turned back on).


Thanks,

Jonathan Hurley
