> Currently, {{CallQueueManager}} has a reference to FCQ which owns scheduler, call queue  and multiplexer. It will make it easier to develop new call queues if scheduler and multiplexer can be made pluggable for reuse. 
>   
> This ticket is opened to define a separate scheduler interface so that 
> 1) different schedulers can be plugged in while using FCQ.
> 2) scheduler related metrics can be easily added for monitoring and trouble shooting.
