Removing symbol table and DRAWF debugging info from release images and binaries #12855
Description
What would you like to be added (User Story)?
We can remove symbol table and DRAWF debegging info from release images and binaries to significantly reduce the size of the images.
Kubernetes does the same for release images: https://github.com/kubernetes/kubernetes/blob/9b9cd768a05782b6cfeef62bec7696b441d7ad93/build/root/Makefile#L89
