I like the above idea that the response body validation will be operated
in REST client. Tempest will be able to check response body anytime and
reduce the test code.

One concern is that Nova API returns different response body when admin
user or not. I'd like to check response body containing attributes what
admin user can get. For example, "get server info" API returns a response
including "OS-EXT-STS" and "OS-EXT-SRV-ATT" attributes when an admin user.

So how about operating the basic validation(without special attributes)
only in each REST client?
The the special validation(such as the above admin info) would be operated
in each test. The schema size for the special cases could be reduced.
