Steven Hardy dbece39f54 Initial support for composable upgrades with Heat+Ansible
This shows how we could wire in the upgrade steps using Ansible
as was previously proposed e.g in https://review.openstack.org/#/c/321416/
but it's more closely integrated with the new composable services
architecture.

It's also very similar to the approach taken by SpinalStack where
ansible snippets per-service were combined then run in a series of
steps using Ansible tags.

This patch just enables upgrade of keystone - we'll add support for
other patches in subsequent patches.

This directory contains Heat environment file snippets which can be used to enable features in the Overcloud.

Configuration

These can be enabled using the -e [path to environment yaml] option with heatclient.

Below is an example of how to enable the Ceph template using devtest_overcloud.sh:

export OVERCLOUD\_CUSTOM\_HEAT\_ENV=$TRIPLEO\_ROOT/tripleo-heat-templates/environments/ceph_devel.yaml
