Emilien Macchi d86025593b Handle undercloud upgrades via host_prep_tasks
Using host_prep_tasks interface to handle undercloud teardown before we
run the undercloud install.
The reason of not using upgrade_tasks is because the existing tasks were
created for the overcloud upgrade first and there are too much logic
right now so we can easily re-use the bits for the undercloud. In the
future, we'll probably use upgrade_tasks for both the undercloud and
overcloud but right now this is not possible and a simple way to move
forward was to implement these tasks that work fine for the undercloud
containerization case.

Workflow will be:
- Services will be stopped and disabled (except mariadb)
- Neutron DB will be renamed, then mariadb stopped & disabled
- Remove cron jobs
- All packages will be upgraded with yum update.

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
