> Enhance blueprints to export placeholder/token for Kerberos-related properties
> Kerberos blueprints can use several hostname properties such as:
> "admin_server_host" in "kerberos-env"
> "kdc_host" in "kerberos-env"
> We should be able to introduce a reference that is exportable and then addressed appropriately with some associated defaults in the cluster template. If these are not specified in the template, it would be an error condition unless there could be appropriate defaults that could be "assumed" based on the cluster host list.
