feat(transparent-proxy): add --exclude-outbound-ports-for-uids

[lahabana]

More possibility for wildcarding to make it easy to exclude everything for a uid

Checklist prior to review

• Link to relevant issue as well as docs and UI issues --
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --
• Do you need to explicitly set a > Changelog: entry here or add a ci/ label to run fewer/more tests?

/golden_files does not work, you need to manually run this, FYI @bartsmykla @lahabana

[lahabana]

@slonka not anymore :) I've taken the time to fix it. Tests like this that don't rely on golden files are frustrating :)

Expected

there is a warning generated somewhere

Yes finally found it. (We were using stdout instead of stderr...)

[lahabana]

@slonka and @bartsmykla I've finally got around to updating this

I only looked at the force pushed diff, looks good 👍
