Determine if provider networks are configured correctly

[Xav Paice]

Need to confirm if for neutron-openvswitch enable-local-dhcp-and-metadata=true, then for neutron-gateway enable-isolated-metadata=true and enable-metadata-network=true. If not, then the dhcp delivered from neutron-gateway hosts will not have metadata.

I'm having trouble grokking this, but I think I get the gist of it.
I think we'd need a way in juju-lint to be able to check the values of configuration items on one charm, dependent on the value of another charm.

With the example provided, if neutron-openvswitch enable-local-dhcp-and-metadata=true, then we would want to ensure neutron-gateway enable-isolated-metadata=true and enable-metadata-network=true were both set?

The pattern which could work for this, in my opinion, is nested rules like -

  neutron-gateway:
   enable-isolated-metadata:
     if: true
       neutron-gateway:
         enable-metadata-network:
           eq: true
         enable-isolated-metadata:
           eq: true

Does that sound like it would address the use case?
