Add releasestatus to static.o.o

Deploy releasestatus under static.openstack.org, as a first step
towards getting rid of the old-wiki.o.o redirection.

The static.o.o releasestatus will be accessible for testing at:
http://status.openstack.org/release.new
If everything behaves properly we'll get rid of the redirect and
make it accessible under http://status.openstack.org/release in a
future commit.

Prerequisite is to complete the git repo move under openstack-infra.
