Allow extra kubectl options to pass through ko apply

[jcrossley3]

Instead of this:
ko resolve -f config/ | kubectl apply -f - -n myns
I'd like to do this:
ko apply -f config/ -n myns

Essentially, pass any unrecognized options through to kubectl apply, excluding those that might be relevant to both, e.g. -f

Does oc also simply pass unknown flags through to kubectl?

It looks like kubectl apply doesn't have an -n flag: https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#apply

I'm not sure it makes sense to ko apply a bunch of config files and overwrite the namespaces each of those configs as we run through them. We might need a better higher-level way to express "install these components in namespace foo" than just passing to ko apply or kubectl apply.

Not too familiar with the innards of oc but I think it's a completely separate beast from kubectl, i.e. I don't believe there is any delegation.

The -n flag is a global option that any kubectl command accepts. See kubectl options
