Erik Språng b3564c1cb2 Back off relative to current estimate rather than ack rate when in ALR. 
If we're in ALR, the acked rate is going to be significantly lower than
the current estimate for the link capacity. If we need to back off in
this situation (usually caused by latency spikes), this CL makes us back
off relative to current estimate if. We then immediately send a new
probe just in case the network did actually change.

All of this is behind experiment flags for now.
