Globalnet Controller support for OVN

[sridhargaddam]

Before working on this, we need to have this ready: #652

The current implementation of Globalnet Controller works with iptables based kubeproxy. We have to add support for clusters that use OVN as the network-plugin driver.

This can be possibly implemented with snat/dnat rules in the submariner_router, although we could always rely to iptables on the host if we need to.

I should be able to implement this relatively easily following the merging of #1689

Adding NAT's to the submariner router is mechanism I would use for now.

This work depends on getting the basic OVN route-agent driver working with Vanilla Submariner working. Once we have that working, we can evaluate if implementing the following interface APIs is sufficient for supporting Globalnet for OVN or if anything else is required.
