Request streaming for HttpComponentsClientHttpRequestFactory [SPR-10728]

[spring-projects-issues]

Arjen Poutsma opened SPR-10728 and commented

The HttpComponentsClientHttpRequest buffers the request contents in memory before sending it over the wire. This can take up significant amounts of memory for large POSTs/PUTs.

It would be nice if we avoid having to buffer request content in memory, but rather stream it directly to the output. We probably want to use org.apache.http.HttpEntity for this purpose.
