Automated passing of the dst ip address from receiver to sender in unicast mode

[David-P-B]

In the nmos node there is no mechanism to autoamtically pass the dst ip address from receiver to sender in unicast mode.
In nmos-js this would currently be done with a manual edit of the SDP file.
It would make sense to automate passing of the dst ip adress in the first step of connection with a unicast Sender!

As discussed on Slack, this can currently be accomplished with nmos-js but means visiting the Receiver to check its active interface_ip and destination_port, then visiting the Sender, using the Edit button to enter these as the destination_ip and destination_port and activating these new parameters, and then going back to the Receiver to connect it to the Sender. Not great user experience!

The Connect tab workflow could be cleverer and attempt to PATCH the Sender before doing the Receiver.
