Upgrade from 2.1.2 to 2.1.3 fails with Security enabled due to missing Accumulo configuration

AMBARI-13295 fixed an issue where, with custom usernames/principals, the Accumulo client was using the default principal to try to authenticate with the Accumulo services with Kerberos enabled. This failed as the client had incorrect information to complete the authentication handshake.

This issue still exists in 2.1.2, however, which causes an upgrade from 2.1.2 to 2.1.3-SNAPSHOT to fail because the incorrect configuration is never corrected.

Robert Levas has kindly pointed that the UpgradeCatalog needs to be changed to ensure that the configuration is updated in the upgrade path out of 2.1.2.
