This looks like something that should be filed as a bug. I don't have
any ideas off hand, bit I will note that the reconnection logic works
fine for us in the upstream upgrade tests. That scenario includes
starting up a full stack, then taking down everything except compute and
rebuilding a new one on master. After the several minutes it takes to
upgrade the controller services, the compute host reconnects and is
ready to go before tempest runs.

I suspect your case wedged itself somehow other than that, which
definitely looks nasty and is worth tracking in a bug.
