This patch adds a check prior to setting the send_periodic configuration
option for the LRP's ipv6_ra_configs to see if the network the LRP is
connected to is a provider network and the port is a gateway port.
In case it is a provider network and the port is a gateway port,
send_periodic should be set to False to avoid leaking the RAs generated
by ovn-controller to the tenant networks onto the provider network.
