Paul Banks d140612350 Fixs a few issues that stopped this working in real life but not caught by tests:
- Dev mode assumed no persistence of services although proxy state is persisted which caused proxies to be killed on startup as their services were no longer registered. Fixed.
 - Didn't snapshot the ProxyID which meant that proxies were adopted OK from snapshot but failed to restart if they died since there was no proxyID in the ENV on restart
 - Dev mode with no persistence just kills all proxies on shutdown since it can't recover them later
 - Naming things

Paul Banks 1e5a2561b6 Make tests pass and clean proxy persistence. No detached child changes yet.
This is a good state for persistence stuff to re-start the detached child work that got mixed up last time.

Paul Banks c97db00903 Run daemon processes as a detached child.
This turns out to have a lot more subtelty than we accounted for. The test suite is especially prone to races now we can only poll the child and many extra levels of indirectoin are needed to correctly run daemon process without it becoming a Zombie.

I ran this test suite in a loop with parallel enabled to verify for races (-race doesn't find any as they are logical inter-process ones not actual data races). I made it through ~50 runs before hitting an error due to timing which is much better than before. I want to go back and see if we can do better though. Just getting this up.
