In order to add vitrage_tempest_plugin to PyPi and to OpenStack CI system,
it must be named vitrage_tempest_plugin. vitrage_tempest_tests was a
copy&paste mistake.
Change-Id: I574414aba16377cc550111b9bcd627c28f04fc49
This tempest plugin is being split out of the main vitrage 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.
