currently a spec like

service_type: osd
service_id: foo
service_name: osd.foo
placement:
  host_pattern: '*'
spec:
  data_devices:
    paths:
    - /dev/vdc
    - /dev/vdd

and a spec like

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

work fine, but

service_type: osd
service_id: xxx
service_name: osd.xxx
placement:
  hosts:
  - vm-00
spec:
  osds_per_device: 2
data_devices:
  paths:
  - /dev/vde

fails with

Error EINVAL: ServiceSpec: 'dict' object has no attribute 'validate'

This is due to handling of the `spec` field along with special conversions of the device selection part of the spec (`data_devices` portion in the examples) that must be transformed into instances of the `DeviceSelection` class rather than just being a dict in order to validate the spec.
