Configuring Kong as an Egress Gateway for Secure Connections to Multiple TLS Servers

[VishalGujela]

Hello,
I'm currently working on configuring Kong as an egress gateway that can securely connect to multiple remote TLS servers and forward HTTP requests accordingly. However, I'm facing challenges in setting up Kong to support multiple server certificates for this purpose. My goal is to preconfigure these certificates so Kong can establish trusted connections with various external services. Any guidance or examples on how to correctly configure this in a declarative (DB-less) setup would be greatly appreciated.
Thanks
