Changed 'kill_idle.sh' to use 'p4 moniter terminate' (not 'kill') idle procs.
This change is to be in line with Support guidance to avoid using direct OS 'kill' on Perforce process IDs. Practically speaking, 'p4 monitor terminate' should have no issue killing IDLE processes.
Also, took advantage of tagged and formatted output to reduce server-side work.
Also, the script will now product output showing pids marked for termination.
