Replacing NetEq discard rate with secondary discarded rate.

NetEq network statistics contains discard rate but has not been used and even not been implemented until recently.

According to w3c.github.io/webrtc-stats/#dom-rtcreceivedrtpstreamstats-packetsdiscarded,
this statistics needs to be replaced with an accumulative stats. Such work will be carried out separately.

Meanwhile, we need to add a rate to reflect rate of discarded redundant packets. See webrtc:8025.

In this CL, we replace the existing discard rate with secondary discarded rate, so as to
1. fulfill the requests on webrtc:8025
2. get ready to implement an accumulative statistics for discarded packets.
