  * [HELP-30196 conference control fix - 4.0 (#3765)  * HELP-30196 fix member count    * HELP-30196 conference control should not rely on destroy event    conference control was waiting for conference-destroy event but if there  are two ecallmgrs, one of them is not going to get the event because of  de-duplication.    since the server was not destroyed, it was getting the commands for the  conference if another instance came alive, but the instanceId is  different and the command was not processed.    a better way to solve this would be to change cb_conferences to issue  the commands to conferences based on the InstanceId (requires changing  the routing key for commands in kapi_conference) and have conference  control bind to InstanceId or Conference.InstanceId](https://github.com/2600hz/kazoo/commit/0f89ea0e21540ade081c345a4d0a96cf38d96ccc) by lazedo
