Subject: [PATCH] v2v: -o rhv-upload: Optimize http request sending
When sending request with small or no payload, it is simpler and
possibly more efficient to use the high level HTTPSConnection.request(),
instead of the lower level APIs.
The only reason to use the lower level APIs is to avoid copying the
payload, or on python 2, to use a bigger buffer size when streaming a
file-like object.
(cherry picked from commit 77a412c0a1cd0e303a072fc5088c8f3bfed36583)
