Split path validation into a separate library
This PR splits path segment validation into it's own package. This cuts off one of the restclient's dependency paths to some docker packages, and completely eliminates its dependency on go-restful swagger validation.

[GarbageCollector] Allow per-resource default garbage collection behavior
What's the bug:
When deleting an RC with `deleteOptions.OrphanDependents==nil`, garbage collector is supposed to treat it as `deleteOptions.OrphanDependents==true", and orphan the pods created by it. But the apiserver is not doing that.
What's in the pr:
Allow each resource to specify the default garbage collection behavior in the registry. For example, RC registry's default GC behavior is Orphan, and Pod registry's default GC behavior is CascadingDeletion.

Add WrapUpdatedObjectInfo helper
This makes it easier to attach checks/transformations to the updated object in storage Update functions, while still keeping the data flow intact (so admission, patch, and other injected checks continue to work as intended), without needing to do anything tricky to get the updated object out of the UpdatedObjectInfo introduced in https://github.com/kubernetes/kubernetes/pull/25787
This is especially useful when one storage is delegating to another, but wants its checks to be run in the heart of the eventual GuaranteedUpdate call.

test: Call forgotten resttest test
PR #3789 introduced this test, but it was never called.
This test was created, but never called.
Written, but never run.
It has neither flaked nor asserted. At its inception it was deserted.
My change gives this test a chance, to at long last finally pass.
The resttest stuff is a bit complicated and I'm not totally sure I put it in the right place @smarterclayton, want to double check this change makes sense?
