Replace with KWOK implementation

Description

After testing, we've confirmed that SimKube works fine with KWOK and so we're ripping out all of the virtual-kubelet-based implementations. This only left skctl as the last remaining bit of Go code in the repo, and so for build tooling simplicity, this has been replaced with a Rust implementation.

Testing done

• manual testing
• make test

Resolves #70, #71
