clean up duplicate code in multiple files

[medyagh]

          excellent work @LJTian thank you for fixing this up ! I look forward to see more contributions from you! one thing that I noiced the docker-env and podman-env files share a lot of code, that is opportunity for more refactor to make them reuse the code instead of duplocation...

@LJTian would you like to assign this for yourself ?

Another location we have duplicate code is in Vfkit Driver and Qemu Driver

The podman-env command is deprecated, you could just remove it?

• Deprecate "podman-env", in favor of using "docker-env" with cri-o #15461

Everything is supposed to use either minikube image or docker-env

Both podman-env and vfkit was copy-and-paste jobs, from the originals...

One, Two, Many (1,2, n)

i.e. refactor on third
