Plan/notes for changes (beta, will be edited and discussed)

• configuration file
  • add mode: origin, edge
  • add server-id: string
  • add origin hostname: ip/fqdn
• global variables
  • listeners_udp = []
• implements UDP_Client()
  • sends data to the udp server
• extends "cm_rtpbcast_session" struct
  • add "relay_type": webrtc, udp
  • add "realy_options" based on type - for UDP would be video-port, audio-port, IP
• extends "cm_rtpbcast_relay_thread"
  • loop additionally over "listeners_udp" array (sessions)
  • call cm_rtpbcast_relay_rtp_over_udp(packet, session) for each listener
• implements "cm_rtpbcast_relay_rtp_over_udp(packet, session)"
  • receives RTP packet to send
  • read UDP destination from "cm_rtpbcast_session": realy_options
  • uses UDP_client to send data
• extends end-point/actions:
  • "watch-udp" (origin + edge mode)
  • add session to the "listeners_udp" array
  • requires to receive the mountpoint definition (ID, video/audio-port, IP)
  • "stop-udp" (origin + edge mode)
  • removes session from the "listeners_udp" array
  • "mountpoint-update" (origin mode only)
  • upgrade session/ws to receive updates about every mountpoint create/destroy

There is also concept of "repeater" but as discussed briefly with @tomaszdurka we could allow the edge mode to be kind of repeater so basically the edge could connect to the edge to add more layers in the topology.

@landswellsong fyi, the orchestration logic which handles replication of mountpoints, starting the watch-udp, reading the state etc will be done in https://github.com/cargomedia/cm-janus/issues/183
