This rewrites 50-heat-docker-cmd to not require any state directory to make decisions on what containers to delete. Instead the labels on the running containers are used to make decisions on when containers should be deleted. This also changes the behaviour to ignore the config name and strictly use the config id, so all containers for a given config id are deleted when that config no longer appears in the list of configs. This maps correctly to heat's software deployment model and allows a future change to properly implement replace_on_change[1] behaviour. Containers created with an older docker-cmd (or create any other way) will never be deleted by 50-heat-config-docker-cmd. This will result in docker run failures when unique container names are re-used and will require manual intervention to delete the old containers before continuing.

Software configuration hooks
This directory contains diskimage-builder elements to build an image which contains the software configuration hook required to use your preferred configuration method.
These elements depend on some elements found in the tripleo-image-elements repository. These elements will build an image which uses os-collect-config, os-refresh-config, and os-apply-config together to invoke a hook with the supplied configuration data, and return any outputs back to heat.
When building an image only the elements for the preferred configuration methods are required. The heat-config element is automatically included as a dependency.
An example fedora based image containing all hooks can be built and uploaded to glance with the following:
git clone https://git.openstack.org/openstack/diskimage-builder.git
