Check add/remove flavor access APIs attributes

This patch adds the JSON schema for Nova V2/V3 add & remove flavor
access APIs response and validate the response with added JSON schema to
block the backward incompatibility change in the future.

The response body of V2 & V3 for add & remove flavor access APIs are same
and given below:

{
    "flavor_access": [
        {
            "flavor_id": "10",
            "tenant_id": "fake_tenant"
        }
}
