Commit Message

allow for three states in the rebuild_gpg_homedirs lockfile

Previously, we had a single lockfile.  This meant we were busy
re-creating the gpg homedirs, so don't duplicate the effort, and don't
try to read from the new homedirs just yet.  Once we were done
rebuilding, we removed the lockfile, so scriptworker could clean up, and
the next rebuild could happen.

However, because there was only two states (locked/unlocked) and there
were potentially three competing actions (rebuild1, scriptworker
copy/cleanup, rebuild2), the latter two raced to see who could fire
first.  And because the copy and cleanup were not instantaneous, having
the second rebuild start nuking the directory before the copy was
finished was a problem.

The solution here is to allow for two states in an existing lockfile
(locked/ready) and the non-existent lockfile makes three.  A nonexistent
lockfile means feel free to launch the next rebuild, first creating the
lockfile.  A locked lockfile means don't read from the new gpg homedirs,
and don't try to launch a new rebuild.  A ready state means feel free to
read from the new gpg homedirs, but don't start a new rebuild yet.
