Reject PATCH VDFs with Services that are not Included in the Cluster
Bugs: AMBARI-21832
https://issues.apache.org/jira/browse/AMBARI-21832
Repository: ambari
Description
-------
Currently there is an odd scenario which can occur when patch repositories are
registered which have services not yet installed. Consider the following
scenario:
- Install ZooKeeper, Storm on HDP 2.6.0.0-1234
- Register/patch a {{PATCH}} VDF for Storm and Accumulo for 2.6.0.1-9999
- Install Accumulo
Which version does Accumulo use - the {{STANDARD}} repository or the {{PATCH}}?
If the {{PATCH}} repository is chosen, this will now prevent reversion of the
patch since there's no prior version for Accumulo to revert back to.
If Accumulo uses the {{STANDARD}} repo, then there needs to be a lot of design
and UX flow work provided to indicate that a {{PATCH}} which was previously
applied can be re-applied for the new service. This also causes problems for
patch reversion since now there would be two upgrades which need to be reverted
to "get rid" of the patch.
For the timeframe for Ambari 2.6, we should reject VDFs that include services
which are not installed. This will prevent the problem.

mvn clean test
UI misbehaves when VDF validation triggers error. Will open a UI jira for that
