Code review comment for lp:~jameinel/launchpad/lp-service

notes from talking this over with spm:

 * at the moment you can see in the process listing which branch is
being accessed; it would be very nice to keep that; but at least we
should log the pid/user/branch
 * can run this on staging, then edge, then lpnet
 * propose changes into lp:lp-production-configs to gradually turn it on
 * might want an rt describing how to monitor the new daemon process,
which just needs to mention the socket location and the hello command;
they can write the script from there
 * francis should formally tell tom and charlie we'll be making this change
