Apply cookiecutter to newly split project

This tempest plugin is being split out of the main manila project in
accordance with Queens goal "Split Tempest Plugins into Separate
Repos/Projects"[1]. This patch applies the standard boilerplate files
for OpenStack projects so that it can stand on its own.

+Prerequisites
+-------------
+
+Before you install and configure the openstack service,
+you must create a database, service credentials, and API endpoints.
+
+#. To create the database, complete these steps:
+
+   * Use the database access client to connect to the database
+     server as the ``root`` user:
+
+     .. code-block:: console
+
+        $ mysql -u root -p
+
+   * Create the ``manila-tempest-plugin`` database:
+
+     .. code-block:: none
+
+        CREATE DATABASE manila-tempest-plugin;
+
+   * Grant proper access to the ``manila-tempest-plugin`` database:
+
+     .. code-block:: none
+
+        GRANT ALL PRIVILEGES ON manila-tempest-plugin.* TO 'manila-tempest-plugin'@'localhost' \
+          IDENTIFIED BY 'MANILA-TEMPEST-PLUGIN_DBPASS';
+        GRANT ALL PRIVILEGES ON manila-tempest-plugin.* TO 'manila-tempest-plugin'@'%' \
+          IDENTIFIED BY 'MANILA-TEMPEST-PLUGIN_DBPASS';
+
+     Replace ``MANILA-TEMPEST-PLUGIN_DBPASS`` with a suitable password.
+
+   * Exit the database access client.
+
+     .. code-block:: none
+
+        exit;
+
+#. Source the ``admin`` credentials to gain access to
+   admin-only CLI commands:
+
+   .. code-block:: console
+
+      $ . admin-openrc
+
+#. To create the service credentials, complete these steps:
+
+   * Create the ``manila-tempest-plugin`` user:
+
+     .. code-block:: console
+
+        $ openstack user create --domain default --password-prompt manila-tempest-plugin
+
+   * Add the ``admin`` role to the ``manila-tempest-plugin`` user:
+
+     .. code-block:: console
+
+        $ openstack role add --project service --user manila-tempest-plugin admin
+
+   * Create the manila-tempest-plugin service entities:
+
+     .. code-block:: console
+
+        $ openstack service create --name manila-tempest-plugin --description "openstack" openstack
+
+#. Create the openstack service API endpoints:
+
+   .. code-block:: console
+
+      $ openstack endpoint create --region RegionOne \
+        openstack public http://controller:XXXX/vY/%\(tenant_id\)s
+      $ openstack endpoint create --region RegionOne \
+        openstack internal http://controller:XXXX/vY/%\(tenant_id\)s
+      $ openstack endpoint create --region RegionOne \
+        openstack admin http://controller:XXXX/vY/%\(tenant_id\)s
