cacheImageUri property
cache_image_uri is the GCR/AR URL where the cache image will be stored.
cache_image_uri is optional and omitting it will disable caching. This URL must be stable across builds. It is used to derive a build-specific temporary URL by substituting the tag with the build ID. The build will clean up the temporary image on a best-effort basis.
Optional.
