Add import for netconf-node-optional
This was missed in the initial work to add the
optional schema first added here:
https://git.opendaylight.org/gerrit/c/netconf/+/82521
Because of that, adding any of the optional configs
(e.g., datastore-lock) to the body of the create device
RPC was failing. importing it in netconf-node-topology
fixes that.
