<pre>[GStreamer] compress property for the HTTP source element
https://bugs.webkit.org/show_bug.cgi?id=143518
Reviewed by Carlos Garcia Campos.
Added a compress property so the default behavior or not
requesting content encoded to the server can be overridden if
needed. This is useful for adaptive streaming playback.
