BlimpClientSession::GetDebugInfo should have a different name, as function
overloading is generally discouraged.

Also, use a callback for returning the result asynchronously (e.g. const
base::Callback<const BlimpConnectionStatistics::StatisticsMap&>&)

Changed to synchronous, since everything is accessed on UI thread.
