Review request for Ambari and Tim Thorpe.
Bugs: AMBARI-20592
https://issues.apache.org/jira/browse/AMBARI-20592
Repository: ambari
Description
-------
ServicePresence check currently checks the following two cases
1. services that do not support upgrade, and must be reinstalled post EU/RU
2. services replaced by other services in the new release, where the old
service must be dropped before EU/RU, and the replacement can be added post the
stack upgrade.
The JIRA is to add one more use case to the check, that;s to check for services
dropped from the new release (end of life)

Testing
-------
unit tests
patch Ambari trunk cluster, update upgrade.xml to include for example YARN as a
removed service, run EU/RU, verify precheck fails and couldn't proceed
(expected)
Thanks,
