Description

1. On ambari-server upgrade to a patch release version (2.0.2 -> 2.2.1.2), ambari server fails to start.
2. This is because the schema version set in the DB on ambari-server upgrade is 2.2.1 whereas ambari-server version is 2.2.1.2.
3. This incosistency leads to DB check failure. DB check should ignore patch release number from the ambari version.
4. Further a clean install on 2.2.1.2 will set the DB schema version to 2.2.1.2 whereas an upgrade to 2.2.1.2 will set the DB schema version to 2.2.1
5. We should fix this inconsistency by always setting DB schema version to 3-digit and ignoring the patch release version during DB check.
6. We will not be supporting DB schema changes in patch releases.
