minyue-webrtc 0c3ca753c5 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.
