Initial release of Host Reservation Admin API by adding new classes
to the current Lease API mapped to /os-hosts/ context.
The goal of this API is to be admin-only, defining CRUD methods for
adding a host to Compute, aiming to dedicate it for lease management.
As a result, the added host won't be available for booting VMs on it
unless Climate specifically picks it from a specific freepool to the
user' pcloud associated with the host reservation.
For testing, please patch RPC methods like this :
call = lambda *args, **kwargs: True
cast = lambda *args, **kwargs: True
TODO :
- Add @policy.authorize() to climate.api.oshosts.service controllers
once review 57200 (Policy mgmt) is merged
Implements bp:host-provisioning-api
