sysdump - Add --cilium-operator-namespace option

[jaredledvina]

Small pull request to allow passing in --cilium-operator-namespace to support use cases where the cilium-operator runs in a different namespace than the cilium-agent.

lgtm. added @aanm and @tklauser as reviewers as well just to double check it's ok to run operator and cilium in different namespaces.

@jaredledvina currently it's not supported installing Cilium Operator on a different namespace other than Cilium. How did you install Cilium Operator in a way that it was running on a different namespace?

Hey @aanm, thanks for the review!

Perhaps I should have renamed this PR to avoid suggesting this is an officially supported configuration. I understand that having the operator and agent in different namespaces isn't officially supported.

In setups where that is the case, it'd be great to have this as an option so that sysdump's do work. This does default to keeping the same namespace as the agent too.

We have a chart that differs from what exists in cilium/cilium in this regard.
