Re: [webrtc-stats] Add stats for the negotiated DTLS-SRTP and DTLS cipher suites.

Is the cert cipher represented by `RTCCertificateStats.fingerprintAlgorithm`, or are you referring to something different?

> Is there a reference to (D)TLS that you can use to give its definition?

`dtlsCipher` would be the selected "cipher suite" as defined in RFC6101, and `srtpCipher` would be the selected "DTLS-SRTP SRTP Protection Profile" as defined in RFC5764.

> How does this tie in to which certificate you used?

The certificates are used for authentication, and (I believe) play a role in encrypting the key that's ultimately used for media.

> Should it be per-transport or per-certificate?

Per-transport.
