[hibernate-dev] Health check status API

[Gunnar Morling]

+1 for looking into the mP health check API.

In fact, I don't even think that Hibernate would have to implement any sort
of looping itself. Instead, the orchestration layer would check the health
check endpoint and automatically restart the service if it's not in a
healthy state. That way, the ordering of start up isn't really an issue,
the application would be simply restarted as often as needed until the DB
is up.
