There are two RTT values reported to GoogCC. They come from the same
source initially but one is calculated and smoothed in the video call stats.
However, there's not really any technical reasons why this value should
be received via the stats, this has just been maintained for legacy reasons.
Experiments shows no real difference between the modes, therefore the
stats-reported RTT is removed in this CL as a cleanup.

Originally RtcEventProbeClusterCreated was logged in bitrate prober. This means that anyone who was using GoogCcNetworkControl wasn't logging it, and the NetworkControl wasn't self-contained.
This changes moves the responsibility for logging ProbeClusterCreated to ProbeController (where the probe is created), it also moves the responsibility for assigning probe ids to the probe controller.

With the current implementation, whenever we are toggling between
sending/not sending retransmissions, the BitrateAllocator will
toggle the total requested max bitrate that is signalled to the
probing mechanism. The result is that spurious probes are sent
mid-call, at |max_bitrate| and |2*max_bitrate|. This behaviour
is undesirable, and thus removed in this CL. Instead, whenever
the allocation limits actually change, we produce a single
set of probes at |max_bitrate| and |2*max_bitrate|.
This CL does not change how the BitrateAllocator hysteresis is
accounting for protection, since it does not relate to the
spurious probes.
