Rename sjc1 mirror to regionone

Current pypi mirror selection uses the actual cloud region from
nodepool, so the attempt to hide the default region name used by
bluebox does not work here.  In the future, we will alter the
format of pypi mirrors to something like
mirror.<region>.<cloud>.openstack.org, but that's a bigger job.
Today, just go with regionone so we can start using bluebox.
