Description

The Docker Remote API response to GET /containers/(id or name)/json changed in version 1.20 and 1.21 from prior versions, changing the location of some fields. Docker attempts to maintain compatibility by dispatching to a versioned function, which functions properly on Linux (with logic to provide the expected values of old fields). However, on Windows, that function just calls the current version instead of the requested compatibility version.

Steps to reproduce the issue:

1. Call the inspect API with the current API version on Linux
2. Call the inspect API with an old (pre-1.20) version on Linux
3. Call the inspect API with the current API version on Windows
4. Call the inspect API with an old (pre-1.20) version on Windows
5. Observe that a Linux daemon returns an appropriate response for the requested version while a Windows daemon returns the current API version response regardless of requested version

Describe the results you received:

A Windows daemon ignores the requested API version and just returns a response appropriate for the current version of the API.

Describe the results you expected:

Expected the Windows daemon to either return an appropriate response for the requested API version or to reject the request for an unsupported API version.
