are we adding this here (instead of updating Krane::DeprecatedDeployTask) to avoid changing KubernetesDeploy::DeployTask?

Could you explain a bit further on exactly what's happening here? Do we only need to worry about (beta), what about alpha groups, or are they not relevant (e.g. we only care about the override group)?

Good point, I've also tried to fix up names and added a comment to make things clearer.

Is this just a sanity check or is there a reason for these 2 in particular?

Just a sanity check, the assert_equal(kinds.length, 13) is the check to ensure list has the right number of items.

This is to fix a bug that was causing resources to have the same name across different tests. Its triggered when the real name was long as the start of two tests were the same. We need the value appended to the name to be stable across tests hence the hashing of @namespace.

What are you trying to accomplish with this PR?
Prune all namespaced kinds by default instead of maintaining a whitelist.
How is this accomplished?
This mirrors #612. However, the latest group/versions doesn't always include all kinds, so I've added an override for the 5 kinds that need it. As far as I can tell there is no kubectl call to get all resources supported version. There is a call to get a resource's supported version making a call per resource seems extreme.
What could go wrong?
This will prune things we didn't before, full list is below..
We may have to keep the override list up-to-date. That being said the list currently contains five items, which is much shorter than the white list it's replacing.
