Add Rust based ovsinit binary

This binary allows us to more reliably migrate IPs, which also
includes routes as well, with proper rollback in place to avoid
a system falling off the network.

This first iteration is used in the Neutron & OVN charts only,
but the long term plan is to leverage it into the Open vSwitch
charts potentially to have a single "auto_bridge_add" source
of truth.
