Add new role for tripleo-validations

This patch allows us to run tripleo-validations tests through the Mistral framework for newton release and above. It also allows us to run negative tests for pre-introspections validations like: - undercloud-ram - undercloud-cpu - undercloud-disk-space The pre-deployment and post-deployment should be done and will be done through different patches.

+Tripleo-validations
+===================
+
+An Ansible role to setup [tripleo-validations](https://github.com/openstack/tripleo-validations)
+
+Requirements
+------------
+
+This playbook expects that the undercloud has been installed.
+
+Role Variables
+--------------
+
+- working_dir: <'/home/stack'> -- working directory for the role.
+- run_tripleo_validations: <False> -- to setup and run tripleo-validations tests
+- run_tripleo_validations_negative_tests: <False> to run negative tests
+- run_tripleo_validations_setup: <False> -- to setup or not tripleo-validations
+- exit_on_validations_failure: <False> -- Exit tripleo-quickstart on validations failure
+- validations_group: <[]> -- The validation group name which should be
+  'pre-introspection', 'pre-deployment' or 'post-deployment'
+
+Dependencies
+------------
+
+No dependencies.
+
+Example Playbook
+----------------
+
+Run the tripleo-validations setup only:
+
+    - hosts: undercloud
+      vars:
+        run_tripleo_validations_setup: True
+      roles:
+         - { role: tripleo-validations, when: run_tripleo_validations|bool }
+
+Run the tripleo-validations tests belonging to the pre-introspection group:
+
+    - hosts: undercloud
+      vars:
+        validations_group: ['pre-introspection']
+      roles:
+         - { role: tripleo-validations, when: run_tripleo_validations|bool }
+
+Run pre-introspection negative tests
+
+    - hosts: undercloud
+      vars:
+        validations_group: ['pre-introspection']
+      roles:
+         - { role: tripleo-validations, when: run_tripleo_validations_negative_tests|bool }
