Remove k8s deps if possible

[jonjohnsonjr]

I added these forever ago to get kubectl flags, but it's been a source of endless trouble...

See #315 (comment) for a recent issue.

This issue is stale because it has been open for 90 days with no
activity. It will automatically close after 30 more days of
inactivity. Keep fresh with the 'lifecycle/frozen' label.

might be able to use https://github.com/kubernetes-sigs/controller-runtime

[jonjohnsonjr]

Can you elaborate a bit?

[dprotaso]

sigh - sorry wrong repo - I meant to link - https://github.com/kubernetes/cli-runtime - that pulls out some common cli logic - ie. flags & reading yaml files

but I realize it depends on k8s upstream libs as well and unfortunately with replace directives :(

[dprotaso]

the replace directives match the versions in the require block so maybe it's just automation playing safe
