There is some ancient redirect we don't control somewhere in Liquid
Web's IP space which has been serving a redirect from
api.openstack.org to developer.openstack.org for who knows how long.
Since we already have a farm of redirect vhosts for other sites on
static.openstack.org, add this one as well so we can clean up this
strange and confusing external dependency.
