Configuring with NETCONF say ok even if config validation fails

Current Behavior

The test continues and fail on something else, in this case, no configuration has been done. But the problem is if you configure multiple snippets of configuration and one fail. You may get the wrong test.

# YANG models downloaded.
ok 1 - Set up topology and attach to target DUTs
ok 2 - Generate WireGuard keys
