📚 Context

cartesi build uses docker buildx build under the hood when building a docker drive.
Buildx support a powerful configurable cache system, including cache support when running in GitHub Actions.

cartesi build does not expose options to configure caching.
Caching would greatly improve build times of cartesi build in CI.

✔️ Solution

Allow a configuration at cartesi.toml docker drive to set --cache-to and --cache-from.

The current possible workaround is to build a docker image without using cartesi build, leveraging cache, and then using cartesi build with a pre-existing docker image with the image toml option.
