    Use Docker healthchecks for core services
    
    This change enables the use of Docker healthchecks for core OpenStack
    services.
    Also check-failures.sh has been updated to treat containers with
    unhealthy status as failed.
    
    Implements: blueprint container-health-check

+    Implements container healthchecks for core OpenStack services. Docker
+    healthchecks are periodically called scripts that check health of a
+    running service that expose health information in ``docker ps`` output
+    and trigger a ``health_status event``. Healthchecks are now enabled
+    by default and can be disabled by setting
+    ``enable_container_healthchecks`` to ``no`` in ``globals.yml``.
