Remove setting of version/release from releasenotes

Release notes are version independent, so remove version/release
values. We've found that projects now require the service package
to be installed in order to build release notes, and this is entirely
due to the current convention of pulling in the version information.

Release notes should not need installation in order to build, so this
unnecessary version setting needs to be removed.

Also, use openstackdocstheme for releasenotes.

This is needed for new release notes publishing, see
I56909152975f731a9d2c21b2825b972195e48ee8 and the discussion starting
at
http://lists.openstack.org/pipermail/openstack-dev/2017-November/124480.html
