Per discussion:
There are no strict rules on allowed/disallowed template configurations. More discussion needed.
This is not a priority right now.

Validation is currently done when launching a cluster, not when creating a template.
When launching a cluster, the appropriate cluster should identify this issue during validate.

There has been some talk recently regarding validation of templates in general.
It is of my opinion that the plugin should be queried during cluster template creation to validate the template. Even if we allow for 'incomplete' templates, the plugin would be able to identify many invalid cluster templates. By flagging invalid templates during creation, this would be much more user friendly as the user would get an exception during launching of the cluster and would need to create new templates since the templates are immutable. After creating a new template, he could again receive an error during cluster launch for an invalid template and he would need to repeat the process. By allowing for validation at creation time, this would prevent this cycle.
