octane does not validate the new template for network roles' changes

[Ilya Kharin]

Octane and the cluster_upgrade extension have to validate the new template for network roles' because any such changes are not supported and can lead to changes of IP addresses.

Steps to reproduce:
 1. Install the 7.0 environment using network template with
        3xController
        3xComputes
        3xCeph-OSD
 2. Upgrade the Fuel Master node to 8.0 and then to 9.0
 3. Change a network for some role
 4. Start the upgrade procedure:
        octane upgrade-env --template=./path/to/changed/template.yaml <env> <release>

Expected results:
 Octane will notify that changing of network roles is not supported and the cluster_upgrade extension also have to validation network roles' changes.

Actual results:
 Octane successfully creates an upgrade environment.
