Updated to use /usr/bin/env python
Added workshop header.
Changed cfg to config.
Initial work to simplify p4_vars and remove cluster stuff.
Testing of named instances surfaced some bugs that are in prod sdp,
now fixed in dev.
Added three triggers from RCJ SDP
Moved p4review.cfg into the new /p4/common/cfg to go along with the
instance_vars files. mkdirs.sh now generates an instance_p4review.cfg
Removed incremental p4verify to clean up a bit. It didn't support replicas
and was really never used.
All port settings now live in <instance>_vars file. You set what you want
the ports to be in mkdirs.sh. There is no more fancy logic to try to guess
what the port should be. You set it, and that is what it is.
Remaining to do is to updated scripts to not need p4master_run. Saved
that work for later since this is tested and works.
