<oo-admin-ctl-usage> Bug 990451, use Mongo config options for Moped session
https://bugzilla.redhat.com/show_bug.cgi?id=990451

oo-admin-ctl-usage wasn't passing the Mongo session options to the
Moped::Session.new call, so certain MONGO_* settings from broker.conf
weren't applied. Thus MONGO_SSL=true had no effect, causing
oo-admin-ctl-usage to fail on systems where Mongo was configured to
use SSL.
