> Original change's description:
> > Move piggybacking controller from P2PTC to DTLS transport
> >
> > The DTLS-STUN piggybacking controller is associated with both the DTLS
> > transport and the ICE transport (P2PTransportChannel). It turned out to
> > be more closely associated with the DTLS transport and requires less
> > plumbing when moved there.
> >
> > The config option to enable the feature remains as part of the ICE
> > transport config since the ICE transport does not know its "upstream"
> > DTLS transport and hence can not query the config from it.
