Support for checksum verification on the ADD instruction

[paraenggu]

The Dockerfile reference has support for checksum verification for HTTP(S) sources while using the ADD instruction, using --checksum. This support was added to the Dockerfile version 1.6.

This offers an elegant and easy way to ensure the integrity of a certain artefact, without having to perform checksum verification using custom tooling within or outside the container image build process.

Are there any plans to add support for this to Kaniko already?

Thanks!
