Add 'detailed' version of the get scheduler_stat.get_pools

[dmbuil]

The openstack_sdk::api::block_storage::v3::scheduler_stat::get_pool::get::Request(), has no way to set the parameter "detail=True", as explained here

This way, instead of just:

{"pools":[{"name":"cinder-2e81b-volume-netapp-fc-alh1-1-0@netapp-fc-alh1-1#volONTAP"}]}"

We'd be getting:

{"pools": [
{"name": "cinder-2e81b-volume-netapp-fc-alh1-1-0@netapp-fc-alh1-1#volONTAP", 
"capabilities": {
   "pool_name": "volONTAP", "netapp_thin_provisioned": "true", 
   "thick_provisioning_support": false, 
   "thin_provisioning_support": true, 
   "netapp_aggregate": "aggr1_SAN", 
   "netapp_is_flexgroup": "false", 
   "netapp_dedup": "false", 
   "netapp_compression": "false", 
    ...
   "allocated_capacity_gb": 499, 
   "cacheable": true, 
   "volume_backend_name": "backend-1", 
   "storage_protocol": "FC", 
   "vendor_name": "NetApp"
}}]}

Maybe a get_detailed could do?

Unfortunately this param in not included in the openapi spec of cinder - actually there is no schema for this method at all. It would need to be added either directly to cinder (unlikely to be fast) or to the codegenerator as vendored schema (can be done fast)
