Description

This allows filters to implement protocols that require application level secret agreement, e.g. origin bound certificates and token binding.

Contributor guide

Research direction
Investigate the existing TLS implementation in Envoy and the filter API. Understand how SSL objects are managed and where the keying material exporter function from BoringSSL should be called. Look at how other similar features are exposed to filters.
