* Address an off-by-one error: the cpu_info field was modified in v2.28,
not v2.27,
* Correct the api-ref to indicate that the 'servers' field is not
actually required and will be missing if '?with_servers=false', while
the 'name' and 'uuid' fields of servers entries *are* required.
* Clarify a comment about the above in the schemas.
* Uncouple the '_hypervisor_response' and '_hypervisor_detail_response'
helper schemas. The minor increase in lines of code is worth it for
the decrease in complexity.
* Add the 'host_ip', 'hypervisor_type', and 'hypervisor_version' fields
to the list of required fields for "detail"-style responses (show and
detailed list).
* Make the 'current_workload', 'disk_available_least', 'free_disk_gb',
'free_ram_mb', 'host_ip' and 'running_vms' fields of the hypervisor
"detail"-style responses nullable, and the 'current_workload',
'disk_available_least', 'free_disk_gb', 'free_ram_mb' and
'running_vms' fields of the deprecated statistics API nullable.
