LU-12722 target: disable recovery for local clients

when client is running on a server node, then the local
services can't rely on that client in the contex of
recovery - such a client dies with the node, can't replay
requests and states and then the restarting server has to
wait till recovery expires which doesn't make any sense.

so the servers should recogize local clients and exclude
them from recovery (i.e. don't make them part of last_rcvd).

for the purpose of local testing a special mount option
"local_recov" has been added to {MDS|OST}_MOUNT_OPTS in
tests/cfg/local.sh to save local testing when everyting
is running within a single node.
