migration: Restart OVS after setting protocols

Browse Source 
This patch is a workaround for bug in OVS [1]. The OVS is restarted
after setting protocols for the integration bridge. This will cause
a data plane disruption. We can remove the workaround once
the bug [1] is fixed.

Closes-bug: #1890596

# By restarting ovs-vswitchd process, new connection is made based
# on the protocols values set in OVS database. OVS 2.13 by default
# implements OpenFlow protocols up to 1.5 and 1.5 is the one that
# is required by ovn-controller.
