p2p_transport_channel: Add estimated disconnected time to CandidatePairChangeEvent

Browse Source 
This patch adds a computed estimate on how long the ice stack
was disconnected before switching to a new connection.

The metric is currently computed as now - max(connection->last_data_recevied())
and has resonably good precision.
