Update cmd flags to support static mpd with live profile

- Deprecated command line flags --profile and --single_segment.
  'segment_template' in stream descriptors implies live profile
  and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
  static mpd for live profile; if not set, dynamic mpd will be
  generated.
