Gael Chamoulaud 255a8b7a9b Improve running prep validations using Ansible documentation 
This patch adds some important export of ANSIBLE_* variables as the
validations playbooks are in their own playbooks directory and are not at
the same level as the libraries, plugins, roles ans so on.

Running validations using Ansible

Validations

You can run the prep validations to verify the hardware. Later in the process, the validations will be run by the undercloud processes.

However, the undercloud is not set up yet. You can install Ansible on your local machine (that has SSH connectivity to the undercloud) and validate the undercloud from there.

You need Ansible version 2 and the hostname/IP address of the undercloud (referred to $UNDERCLOUD_HOST here):

$ sudo yum install ansible
$ git clone https://git.openstack.org/openstack/tripleo-validations
$ cd tripleo-validations
$ printf "[undercloud]\n$UNDERCLOUD_HOST" > hosts
$ export ANSIBLE_STDOUT_CALLBACK=validation_output
$ export ANSIBLE_CALLBACK_PLUGINS="${PWD}/callback_plugins"
$ export ANSIBLE_ROLES_PATH="${PWD}/roles"
$ export ANSIBLE_LOOKUP_PLUGINS="${PWD}/lookup_plugins"
$ export ANSIBLE_LIBRARY="${PWD}/library"

Then get the prep validations:

$ grep -l '^\s\+-\s\+prep' -r playbooks

And run them one by one:

$ ansible-playbook -i hosts playbooks/validation-name.yaml

Or run them all in one shot:

$ for PREP_VAL in `grep -l '^\s\+-\s\+prep' -r playbooks`; do echo "=== $PREP_VAL ==="; ansible-playbook -i hosts $PREP_VAL; done
