Failed to validate Drive Group: OSD spec needs a `placement` key.

[Ted Lum]

During openstack deploy...

cephadm fails with "Failed to validate Drive Group: OSD spec needs a `placement` key." when applying ceph_spec.yaml, generated by /usr/share/ansible/plugins/modules/ceph_spec_bootstrap.py.

Apparently, given my configuration and version specifics, cephadm requires a placement key; i.e.

---
data_devices:
  all: true
placement:
  host_pattern: '*'
service_id: default_drive_group
service_name: osd.default_drive_group
service_type: osd

which will not be generated by /usr/share/ansible/plugins/modules/ceph_spec_bootstrap.py.

With a simple change I got passed the issue:

but I have no idea how many other valid configuration permutations there are or how this change would or would not adversely affect them. I'll leave a proposed remediation to those far more knowledgeable than I.
