Generates M3U8 for HLS playback

[haudiobe]

Script could be amended to also change to an M3U8 playback. We may use parts of the DASH-HLS playback github repository.

This issue relates to the front end to be able to playback the test content in hls and dash. Someone should create an hls manifest for each test content. Preferably done on the fly - using DASH-HLS Interop recommendations.
