Contributions summary:Michael focused on improving the `hoplite` Kotlin configuration library. Their contributions included fixing resource stream handling by implementing `.use` to ensure streams are closed, and refactoring of resource loading including allowing overriding of the classloader, and providing abstraction around how we load resources. They also updated the project to use Kotlin 1.6.10 and JVM toolchains and made the testing of property sources more robust.
