This adds a new mode to the ProbeController that sends probes every
second the first 5seconds. Intented usage is before normal media has
started flowing. If enabled, the max allocated bitrat is ignored during
these initial probes.
The purpose is to have a more accurate estimate at the beginning of a
call.
The cl also removes ProbeController::SetFirstProbeToMaxBitrate.

This reverts commit 501c4f37bf.
Patch set 1 contains pure reland.
The reason why we want to do this is because audio can allocate a needed bitrate before video when starting a call, which may lead to a race between the first probe result and updating the allocated bitrate.
That is the, initial probe will try to probe up to the max configured bitrate.

Instead of disabling probing when the total allocated bitrate has
changed in goog_cc, it can be done via a new field trial parameter,
"probe_max_allocation". Not that the currently used flag
RateControlSettings::TriggerProbeOnMaxAllocatedBitrateChange() is per
default enabled and will be cleaned up in a follow up cl.
The field trial flag "skip_if_est_larger_than_fraction_of_max" now also
skip probing if the current estimate is larger than the currently max
allocated bitrate. ie, alr probing is skippe if the current estimate >
max configured bitrate or current estimate > max send bitrate of all
streams.
