--use-wheel was deprecated in favor of --only-binary in pip v7.0.0. and
--use-wheel was removed in a recent release of pip. but some packages
are source packages, so we cannot simply replace use-wheel with
only-binary. so a simpler approach is to drop --use-wheel option, as pip
respects --find-links, and will find the required package from the
wheelhouse.

When doing rbd-nbd map, if the Ceph service is not available,
the codes will wait on rados.connect(), unless killing the process.
In that case, the close_nbd logic is skipped with NBD_CLEAR_SOCK ioctl
not called. On the CentOS 7 kernel, it leaves nbd->file not cleared, which
causes the subsequent map requests return EBUSY, this patch fixes it
by connecting Ceph first prior to calling NBD_SET_SOCK ioctl
