Avoid running chef automatically
Avoid running chef automatically

teuthology --lock formerly automatically ran chef on startup of
virtual machines. This covered up a bug where ceph-deploy would
not install properly. These changes remove the automatic running
of chef, and fixed some related issues when setting up keys on
virtual machines.
