reproducer - cifmw_ci_nmstate_instance_config - ipv6

Use cifmw_devscripts_config.provisioning_network to set the ip address
for the `ocppr` bridge. If not set, use the default first address in
172.22.0.0/24.

Also check the ip version, and set nmstate yaml up to configure the
correct version, and disable the other version.
