Public bug reported:
Running from stable/folsom in preparation for 2012.2.1, nova-compute
fails to start using the same config thats been working fine with folsom
so far.

Tracked down to this change that looks to be cherry-picked directly
from master into stable/folsom: https://review.openstack.org/#/c/16432/
Here, the compute_driver flag was moved to the global flags to fix
another issue, but its default value
(default='nova.virt.connection.get_connection') is dropped with the
move. Without it, installations that have been using connection_type
for the last two releases to set compute flavor start with no manager
set.
