Subject: [PATCH] feature: capture HTTP version in Request

This allows responding with info about the HTTP version.

Additionally, expanded a test to cover this.

Note: in the test, we assert resp.version(). However, for my use case I
have `test client --> reverse proxy under test --> wiremock`, so I do
not have direct access to the response from wiremock. Hence, I want to
put more info about the request into the response body/headers.
