Raja Subramanian 7fef374b19 Split down stream snapshot into sender view and receiver view. (#3422)
Receiver view is used for connection quality.

Sender view is used for analytics. One thing that this introduces is
that sender view uses the packet loss information from receiver view as
true loss is available only in the RTCP Receiver Reports received from
the remote side. So, the time alignment is off, i. e. receiver report
happens periodically and it includes information till the time at which
it was sent from remote side, but sender could have sent more packets
after that time.

The split should ensure that analytics does not rely on remote side
sending proper receiver repoerts albeit at slight misalignment of loss
statistic for remotes that send RTCP RR (which should be majority of the
cases)
