Data classification note: This patch introduces a new decoding mechanism and extends the telemetry introduced in https://phabricator.services.mozilla.com/D211194. The metrics that are still under Category 2 “Interaction data”. The metrics measure the user interaction with the certificate compression decoders. In this patch we check how often the users were using the certificate compression feature using the zstd decoder and what's the performance gain (amount of bytes saved during the TLS handshake).
