[Bug 1823282] [NEW] optimize reload of openvswitch-switch

[James Page]

Public bug reported:

A reload of openvswitch-switch is particularly disruptive to existing
network flows resulting an a 10 second or so pause while the datapath
rebuilds.

Its possible todo a more optimized flow save/restore and orchestrated
restart of the ovs daemons to minimise and disruption to a second or two
at most.
