Ghanshyam Mann b26bc7fd7a Multiple API cleanup changes
This microversion implements below API cleanups:

1. 400 for unknown param for query param and for request body.

2. Making server representation always consistent among all APIs
   returning the complete server representation.

3. Change the default return value of ``swap`` field from the empty string
   to 0 (integer) in flavor APIs.

4. Return ``servers`` field always in the response of GET
   hypervisors API even there are no servers on hypervisor

Details: https://specs.openstack.org/openstack/nova-specs/specs/train/approved/api-consistency-cleanup.html

Partial-Implements: blueprint api-consistency-cleanup
