This would alleviate problems in (non-stacked) physical switches, due to rapid
movement of MAC addresses between links.

We do this only on ovs, because the linux bond mode does not support
changing the rebalance-interval (it is fixed at 10s).

It is (still) possible to override this by setting
PIF.other_config:bond-rebalance-interval (in ms), followed by a PIF.plug.

Tested in both the ovs and Linux bridge mode by creating and destroying
a bond, and inspecting the rebalance interval in the ovs case (ovs-vsctl
list port).
