Bug Description
Observations:
* regiond, when restarted rapidly (e.g. in the CI test script), can get
wedged during start-up. A symptom is that RPC endpoints are open and
listening but the /rpc/ advertising page is not available (HTTP 503).
* This only seems to happen on Trusty; CI ran on Utopic for a while and
this problem was not observed.
* The tasks in m.start_up are called by WebApplicationS
starts but should, ideally, be called earlier, as part of the
bootstrap sequence in m.plugin.
This problem may be caused by a combination of factors, for example
Upstart on Trusty and ordering of start-up tasks within regiond.
As a first step to understanding this bug (and maybe even fixing it) I
suggest that we move the start-up tasks in m.start_up to regiond's main
bootstrap sequence.
