Trying out cargo chef and a travis docker image cache. (#1238)

* Trying out cargo chef and a travis docker image cache. * trying to change internal target. * Use latest cargo-chef with --target * Remove caching for now. * Adding back in chowns * Adding back in cache. * Remove travis caching. * Switching dev dockerfile to match prod, using cargo-chef and alpine. * Make travis happy * Trying a chown rust. * Caching cargo-chef first. * Moving the chowns * Removing many copy commands. * Go back to rust 1.47.0 due to config-rs breaking. * Adding the old volume mount version. * Adding some script comments.
