core: Log level changes do not effect on running client process
Problem: commit c34e4161f3cb6539ec83a9020f3d27eb4759a975 set log-level
per xlator during reconfigure only for a brick process not for
the client process.
Solution: 1) Change per xlator log-level only if brick_mux is enabled.To make sure
about brick multiplex introudce a flag brick_mux at ctx->cmd_args.
Note: There are two other changes done with this patch
1) Ignore client-log-level option to attach a brick with
already running brick if brick_mux is enabled
2) Add a log to print pid of the running process to make easier
debugging
