> Add an API directive to force toggling Kerberos if the cluster's security type has not changed.  
> This is useful for _retry_ attempts to enable or disable Kerberos when the workflow progressed far enough to store the _new_ security type.  
> Trying to enable Kerberos when the cluster's security type is already set to {{KERBEROS}} will result in a successful response from the Ambari server but no actions will be performed.  Same for attempting to disable Kerberos when the cluster's security type is already set to {{NONE}}.  
> By forcing the operation using the {{force_toggle_kerberos=true}} directive, the security type check is avoided, thus allowing the _retry_ operation to proceed. 
> Example: 
> {code}
> PUT /api/v1/clusters/CLUSTER_NAME?force_toggle_kerberos=true
> {
>   "Clusters" : {
>     "security_type" : "KERBEROS"
>     }
> }
> {code}
