[remoting host] Enable client to request ICE restart.
If SDP re-negotiation is needed (for example, to configure a different
video/audo codec), ICE needs to be restarted. But the client cannot do
this directly, because the host is the end that sends the initial SDP
offer.
This CL adds a control message that the client can use to request ICE
restart from the host. This is only implemented for WebRTC connections.
