to prevent continuously recording a meeting whe someone forgets to logout

 - make errors consistent
 - return back createTime on a create API call
 - require createTime parameter on a join API call. This way users with stale join link won't be
   able to join a running meeting.

   especially if the meeting is recorded.

 - make the length of the blank video into a float instead of int. This way we hope to have
   a blank video with 8.74sec long instead of 8sec long.

   instead of relying on status event

 - need to add jedis plugin so we can store the start/stop broadcast event
   as the webcam status event is unreliable and can introduce sync issues.
