Use explicit timeout instead when the network
just drops any packet.

This quirk allows for software aborts after a configurable number of
sk_{snd,rcv}timeo events.

This cannot work in case of split brain.
Therefore, some primary must be designated always explicitly.

marsadm: allow overrides of "marsadm secondary" in disconnected clusters
...
When the communication is down in partitioned clusters, the command
"marsadm seconodary" would normally use the current timestamp of
the command execution for the Lamport update protocol.
Make an exception for the case that a concurrent "marsadm primary"
was given somewhere else on a disconnected / partitioned node: let
the "primary" always win over a "secondary" command.
