Network templates and network groups are not covered in CLI reference docs

[Aleksey Kasatkin]

We have partial description of CLI commands for network templates and network groups here: https://docs.mirantis.com/openstack/fuel/fuel-master/operations.html#using-networking-templates

It's required to make description of all commands and flags and place it into CLI reference: https://docs.mirantis.com/openstack/fuel/fuel-master/user-guide.html#using-fuel-cli
