Description

Implement the ability to disable Kerberos from a cluster that was previously configured for Kerberos.

This entails reverting configuration properties set when Kerberos was enabled to default values found in the stack.

Principals will not be destroyed in the KDC and ketyab files will not be removed from hosts.
