This patch introduces a new microversion to identify services by uuid
instead of id, to ensure uniqueness across cells. GET /os-services
returns uuid in the id field, and uuid must be provided to delete a
service with DELETE /os-services/{service_uuid}.
The old PUT /os-services/* APIs are now capped and replaced
with a new PUT /os-services/{service_uuid} which takes a uuid path
parameter to uniquely identify the service to update. It also restricts
updates to nova-compute services only, since disabling or forcing-down
a non-compute service like nova-scheduler doesn't make sense as it
doesn't do anything.
The new update() method in this microversion also avoids trying to
re-use the existing private action methods like _enable and _disable
since those are predicated on looking up the service by host/binary,
are confusing to follow for code flow, and just don't really make sense
with a pure PUT resource update method.
