ESS-1454: Implement acknowledgement of answer message

ishannaithani commented 5 years ago

Purpose of this PR:

To support new MCU with JS SDK, MCU needs to be notified when SDK clients have completed the SDP negotiation process i.e. successfully/unsuccessfully setRemoteDescription in answerHandler. To enable this, a new SIG_MESSAGE_TYPE is created answerAck to be sent to MCU.

Created a function acknowledgeAnswer
Calling acknowledgeAnswer in answerHandler success and failure callbacks with respective parameters.
Message is sent only if MCU is in the room (target is MCU).

See ESS-1454 for more details.
