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.

Currently, we have a lot of logic for checking if a handler should run,
depending on whether config files have changed and whether the
container configuration has changed. As rm_work pointed out during
the recent haproxy refactor, these conditionals are typically
unnecessary - we can rely on Ansible's handler notification system
to only trigger handlers when they need to run. This removes a lot
of error prone code.

This patch removes conditional handler logic for all services. It is
important to ensure that we no longer trigger handlers when unnecessary,
because without these checks in place it will trigger a restart of the
containers.

Add a new variable 'kolla_devmode', which when enabled, clones and
bindmounts service source code into the containers.

This commit adds the relevant changes for Heat, more services can be
added and built upon.

Usage:
* Set 'kolla_devmode: yes'

* Code is cloned to /opt/stack/{{ project_name }} on target
  node(s)

* Users can develop in these repos, and simply restart the container to
  pick up / test changes.

Debugging can be done from the host via 'remote_pdb'[0].

A config generation check was added to a few services but the action
name checked was "genconfig" where the kolla-ansible genconfig command
actually uses the action name "config".

Stop run the handlers when action is "config".
