[Policy Assistant] kubectl plugin support

[MrHohn]

Happened to come across the first Policy Assistant release (congrats!) and learned that it was derived from the Cyclonus project.

Wondering whether adding the kubectl plugin support is on the roadmap? Something similar to https://github.com/mattfenwick/kubectl-cyclonus.

A kubectl plugin for policy assistant sounds like a good idea. I didn't know that Matt already made a plugin for cyclonus, that's great. Let me ask folks in SIG netpol API where they think plugin code ought to be. I'll probably post an update in late Jan after the holidays.

@mattfenwick did you have to make any changes to cyclonus to support the kubectl plugin or did it work out of the box as a wrapper CLI for the analyze command?
