Nova conf hardcoded to 'nova' user with 'external ceph'

[Nathan Harper]

When using the 'external ceph' functionality, the ceph usernames and pools can be configured for each Openstack service.

For nova, it is looking explicitly for keyrings called ceph.client.nova.keyring and ceph.client.cinder.keyring.

If you are using an existing Ceph cluster, there is a good chance that you will not be able to use the default usernames.

If you can remind me of the process, I'm pretty sure I could patch this

This appears to be fixed in current versions:

1082 # External Ceph keyrings
1083 ceph_cinder_keyring: "ceph.client.cinder.keyring"
1084 ceph_cinder_backup_keyring: "ceph.client.cinder-backup.keyring"
1085 ceph_glance_keyring: "ceph.client.glance.keyring"
1086 ceph_gnocchi_keyring: "ceph.client.gnocchi.keyring"
1087 ceph_manila_keyring: "ceph.client.manila.keyring"
1088 ceph_nova_keyring: "{{ ceph_cinder_keyring }}"
