update and resolve conflicts
Resolve TODO (util has been updated).
Removed the cylc lockserver.

This was a legacy requirement on the initial implementation of cylc
at NIWA. It is not really necessary under the new "installed suite"
paradigm (if at all) and it is longer used even at NIWA.
Removed the old housekeeping utility.

It is not worth updating this right now for cylc-6 as it has a known
major deficiency aside from assuming old-style cycle times - it can't
housekeep individual files below a cycle time labeled directory.
Address stop command stop point validation.
Removed broken manual test code.
