Http2! (it's actually h2c)

Jira

https://clever.atlassian.net/browse/INFRANG-5794

Overview

Took some examples from https://github.com/aws/aws-app-mesh-examples/blob/main/walkthroughs/howto-http2/color_server/main.go#L85-L89.

We use envoy for TLS handshake for internal services and for external services the TLS is terminated by the ALB so our wag servers need to use h2c (which is http/2 - TLS)

Todo

• [x] Run make build
• [x] Run make generate
• [ ] Update the current version in the /VERSION file.

Testing

Deployed sso-il-token-service with these changes in tanmay-dev. And with the help of https://github.com/Clever/catapult/pull/2155 tested that http2 works!

I am also going to run a staging load test!
