> Add a way to compute whether an execute-stage should be included, other than the simple
service/component check.  
> For example some stage should only be executed if the cluster has Kerberos enabled. 
This can be determined using the {{cluster-env/security_enabled}} flag; or (better yet) the
{{Cluster}}'s {{securityType}} property, which would be set to "KERBEROS".
> Currently the only filter is based on service and component, which does not work in the
case of Kerberos since Kerberos can be enabled without needing to install the KERBEROS service
or the KERBEROS_CLIENT component. This will happen if the Kerberos identities are managed
manually rather than configuring Ambari to do it by integrating with a supported KDC.
