category expansion can only come from the server
A couple release ago we moved category expansion to the server instead of hardcoding it in the client. Similar to restmappings, there is no valid client-side expansion anymore, so this removes the code that hardcoded the list and moves the category expansion to the same package as our discovery based restmappers.

Exclude keys containing empty patches in the final patch
**What this PR does / why we need it**:
This minimizes the 3-way JSON merge patch generated when calculating the patch necessary to send to the server. It does this by removing empty maps created from deleting keys in the keepOrDeleteNullInObj method.
This is not only a slight performance improvement (less PATCH requests) but also necessary when working with custom resources that have RBAC restrictions.

push ToRESTMapper down a layer
The RESTMapper is needed to drive some use-cases for a dynamic client and takes a little bit of wiring (nested restmappers). This pull pushes that into information derived from the kubeconfig flags to allow easy re-use.

default the ignorenotfound for delete when selecting objects
When selecting resources and then deleting them (as opposed to specifically indicating a resource to delete) we should default to not failing if something disappeared partway through. This is quite common when label selecting deletes and GC runs before you get to a dependent object.
I also took the liberty of doing complete work in complete instead of validate.
```release-note
`kubectl delete` with selection criteria defaults to ignoring not found errors
```

stop using Info.Mappings when they may not be present
On a resource builder, you cannot logically have a RESTMapping or a Client if you're running a local action. Reliance on the `info.Client` and `info.Mapping` is a bug we need to fix. This updates the docs and eliminates unnecessary reliance. Other hits I found didn't have `--local` options, so we're safe or had them and and were already broken. I think we'll be able to help them after making our creation flow obvious.
