Auto adjust sender stream based on consumers usage

[giangndm]

For optimizing resource usage in sender side, we should have some thing like auto reduce or turn-off sender stream.

The ideally logic is:

• No one watch the stream => disable send
• Some other watching with condition: max layers, max allocated bitrate => don't send waste data which don't used by any consumer

Thank you. From client side there should have option to disable/pause stream. This could be done either by a dedicated option or simple video pause. If option done by video pause then there have possibility user may play again. So, having a dedicated option will be better. From JS side can be use IntersectionObserver to determine the visibility of the video and pause when necessary.

@jibon57 I think we can add something like IntersectionObserver with ts-sdk attach/detach. or pause/resume when it complete (8xFF/atm0s-media-sdk-ts#20).
