bridge: Keep bond active slave selection across OVS restart
Whenever OVS restarts, it pseudo-randomly picks an interface
of a bond port to be the active slave. This can cause traffic
disruption in case the upstream switch does not support LACP, or
in case of multi-chassis switches that do not support mLACP.
This patch helps the situation by always record the last active
slave into ovsdb. When OVS restarts, the stored last active slave
has the highest priority to be selected again. In case this interface
is available, due to configuration changes or being offline, OVS then
consider other interfaces with the bond as it does today.
In a nutshell, this patch makes the active slave selection stickier
across OVS restart.
