> While implementing some of the upgrade checks which were removed as part of
> AMBARI-24737, the SPI needed some extra information added.
> - Some checks used {{VersionUtils}}, so this needed to be relocated to the
> SPI.
> - Added service-level repository version information to {{ClusterInformation}}
> - Simplified the {{UpgradeCheckDescription}} when there is only 1 failure
> message.
> - Prevent NPE when {{CheckQualifications}} is {{null}} (even though Javadoc
> says it must return an empty iist.
