Add API schema for v2.1 block_device_mapping extension

Browse Source 
By defining the API schema, it is possible to separate the validation
code from the API method. The API method can be more simple.
In addition, a response of API validation error can be consistent for
the whole Nova API.

Partially implements blueprint v2-on-v3-api
