Support for client-side apply

[KaoruDev]

Is there a reason why client-side apply is not supported? I know that server-side apply is better, but my current team uses clients like Lens to manage their workloads. Testing it locally I believe Lens uses client-side apply. Looking at the managed_fields property reveals that client-side apply changes the field manager from the original field manager.

I suppose I can just use --server-side --force-conflict for now until we migrate everything? Is that the suggested migration path? I'd be happy to add it to the README.md if it is.

Cluster version: 1.18
Client version: 1.22

Mainly because nobody implemented the necessary logic in kubeclient :-). PRs welcome.

I don't know enough to comment on safety of mixing the two and --force-conflict...

See #358 for previous discussion and links.

There are two parts there:

• if you want to start from a yaml file with arbitrary resource types, kubeclient is missing the plumbing to create apporpriate Client objects.
• the merging logic itself, given a Client object for correct API group and a desired state.
