> Create API entry point to initiate Kerberos keytab regeneration for the cluster:
> {code}
> PUT /api/v1/clusters/{clustername}?kerberos_regenerate_keytabs="true"
> {code}
> The entry point should invoke code to determine which principals need to be updated and
then generate the following stages:
> # Update Principal Passwords
> # Generate Keytabs
> # Distribute Keytab
> This could be done in a method within {{org.apache.ambari.server.controller.KerberosHelper}}
named {{regenerateKeytabs}} and flow similarly to {{org.apache.ambari.server.controller.KerberosHelper#toggleKerberos}}
> A Server-side action implementation already exists for generating keytabs - see {{org.apache.ambari.server.serveraction.kerberos.CreateKeytabFilesServerAction}}.
> A process is already in place to distribute keytabs - {{org/apache/ambari/server/controller/}}
> A new Server-side action _may_ need to be created to update relavant principal passwords,
however {{org.apache.ambari.server.serveraction.kerberos.CreatePrincipalsServerAction}} may
work for this, unaltered.
