socket: use TCP_USER_TIMEOUT to detect client failures quicker
Use the network.ping-timeout to set the TCP_USER_TIMEOUT socket option
(see 'man 7 tcp'). The option sets the transport.tcp-user-timeout option
that is handled in the rpc/socket layer on the protocol/server side.
This socket option makes detecting unclean disconnected clients more
reliable.
When the socket gets closed, any locks that the client held are been
released. This makes it possible to reduce the fail-over time for
applications that run on systems that became unreachable due to
a network partition or general system error client-side (kernel panic,
hang, ...).
It is not trivial to create a test-case for this at the moment. We need
a client that unclean disconnects and an other client that tries to take
over the lock from the disconnected client.
