Use zstd for compression

What does this MR do?

This MR adds the ability to disable or enable the use of the ZStandard compression algorithm when building docker images.

Zstandard compression is a feature supported in ContainerD. Zstandard benchmark shows zstd is >3x faster decompression than gzip (the current default).

It is 5x faster in compression speed as well in comparison to gzip.
