- make sure listen only users are muted

 - make sure liten only user is muted when they join voice conf

Set the default recording codec to opus since we now have opus support in freeswitch.

 - set audio recording codec to ogg so file size will be smaller compared to wav

 - poll FreeSWITCH for status of user so that akka-apps would be in sync with FreeSWITCH

 - We had an issue where FreeSWITCH, for some unknow reason, stopped recording the voice conference
   in the middle of the meeting while there are users in the voice conference. We've relied on the
   voice conf started event to trigger recording of wav files. This event is sent when the first user
   joins the voice conference. In this case, there was no voice user joined after the recording stopped
   as there were already users in the voice conference. TO make sure that the audio is recorded, akka-apps
   will send a "check if voice conf is running and recording" message to FreeSWITCH every 30sec. If akka-apps
   receives a "running=true recording=false" response from FreeSWITCH, akka-apps will send a start recording
   msg to FreeSWITCH.

 - stop recording of voice conference when meeting ends.

 When chapterBreakLengthInMinutes > 0 in /usr/share/bbb-apps-akka/conf/application.conf, the
 chapter break is triggered even when the meeting isn't set to be recorded.

 Check if meeting is to be recorded before triggering chapter break.
