feat(test-tooling): rust compiler container for wasm builds

Uses the stock rust container image from DockerHub
Can do regular cargo builds and wasm-pack as well.

This can be used to author test cases related to the API
server being able to load WASM modules as Cactus
plugins in the near future (this commit is part of the
effort to build out the scaffolding of tests prior to
getting the actual feature implemented)
