kubectl debug: allow users to specify debugging profile

[knight42]

This is the tracking issue for the implementation of debugging profile feature of kubectl debug.
Ref: https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/1441-kubectl-debug#debugging-profiles

There are multiple profiles that we need to handle, and I plan to file a single PR for each profile:

• legacy: refactor(kubectl): add ProfileApplier interface for kubectl-debug kubernetes#105008
• general: kubectl-debug: add more debugging profiles kubernetes#110526
• baseline: kubectl-debug: add more debugging profiles kubernetes#110526
• restricted: kubectl-debug: add more debugging profiles kubernetes#110526
• sysadmin
• netadmin
• auto

@verb I am not certain about what isolated namespaces and private namespaces actually means, could you please elaborate more on them? What is the difference between them?

@knight42 I like that you're planning on implementing the profiles incrementally. iirc the namespaces are referring to shareProcessNamespace.

@knight42 what's your availability to work on the general profile? I have some time to start working on it, too.
