ceph-disk: encryption assumes admin key is present
When testing the ceph-disk in jewel new behavior was noticed where it assumes an admin key is present on all the osd servers. When Ceph is deployed with juju we by default do not include the admin key on the osd servers. We only include a bootstrap key. I'm working on creating a small patch for ceph-disk where it has an --id option for ceph-disk prepare so that the create_key function can do the initial config-key put. I'd like to have a key on the osd cluster that only allows config-key put for this initial setup operation and tell ceph-disk to use that.
