Add log channel just for all the Cmd{In,Queued,Done} keys.

tron has logs of all traffic gong through it, one per actor, etc. For the command channels, that includes keys describing the commands when they come in to tron, whether they get dispatched to the target actors, and when/how they finish.

Add a single log channel for all of these. As it stands we either have to look in the archiver or in the per-commander log files.
