Request for template group

It would be nice to have a template group, similar to other template components. It would give more dynamic group creation inclusion and exclusion.

Jinja supports returning a list which is what the regular group definition expects for entities

group:
  template_group:
  name: A template group
  entitties_template: >-
    {{ (states.zwave
      | selectattr('attributes.battery_level', 'defined') 
      | map(attribute='entity_id') 
      | list) 
    }}

I think as long as the template returns a list, it should be possible.
