Apply cookiecutter to newly split project

This tempest plugin is being split out of the main neutron 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.
