Description

Adding services when Kerberos is enabled incorrectly changes unrelated service configurations. For example, kerberos-env/service_check_principal_name is changed from "${cluster_name|toLower()}-${short_date}" to a concrete value like "c1-072818".

This is a regression created with the resolution of AMBARI-23292.
