HTTP API for public SSL certificate

[alexkalish]

Functional User Story

As a Kubernetes operator
I want an HTTPS REST API for fetching the Conjur node’s public SSL certificate
So that I can easily and programmatically fetch it when configuring a K8s cluster

Additional Details

• This will definitely require approval/review by a security architect.
• Please practice README-driven UX, so that PO + team can review before implementation.

Implementation/Solution Notes

[izgeri]

The dev team landed on different strategies for retrieving the Conjur SSL certificate programmatically: see #2038. As these will be implemented in cyberark/conjur-authn-k8s-client#232, I am closing this card now.
