A few minor enhancements

[lowecg]

Added deps.edn to support git dependencies Added a feature to support the use of reverse proxies (e.g. ngrok) by overriding the hostname in HTTP calls (the original hostname is still used for the signing process). This enabled me to use clj-oauth from AWS Lambda to target a local test service Wrapped eagerly instantiated secure resources with delay to support GraalVM native compilation.
