[discovery] Rewrite DiscoveryIE (fixes #5898)

Browse source 
Discovery.com now uses a completely different approach for serving
videos. At least in both test cases brightcove are involved. However,
AMF support is necessary for these brightcove videos. As a result, I
try to extract videos from the info page ('?flat=1'). The downloaded
file can be different from the one in browsers.
