Ability to see the effective envoy configuration
EnvoyConfig does some processing on the logic and merges multiple parts to create one cohesive configuration, which is then served to the envoy. However, as a user, when I am debugging an issue with a config, it would be a great addition if I could see the effective configuration, which I could use in a non-marin3r deployment or verify in pure envoy (e.g. to report a bug, to get help on official channels etc.).

related to this, might be worth taking a look at https://github.com/lidizheng/proposal/blob/csds/A40-csds-support.md
I'm late to this discussion, but if I want to see the Envoy config I usually dump the contents of the current envoyconfigrevision.marin3r.3scale.net CR.
