Many of the files in qa/qa_scripts/openstack had incorrect shebang
lines: the bang was missing. This means that those scripts would
execute using the calling user's login shell, which is doubtless not
what the author intended. Now they'll always use bash.
Two scripts do not need shebangs, because they contain only library
functions and don't execute anything. I removed their shebangs.

A set of scripts used to bring up an OpenStack instance on one site,
connect a ceph cluster, add pools to store OpenStack glance images,
cinder volumes, nova vms, and cinder backups on rbd, and bring up a nova
compute node.
