This commit performs two refactors and fixes a bug.
Refactor 1 changes the signature of Request to take a RESTClient, which
removes the extra copy of everything on RESTClient from Request. A pair
of optional constructors are added for testing. The major functional
change is that Request no longer has the shim HTTPClient interface and
so some test cases change slightly because we are now going through
http.Client code paths instead of direct to our test stubs.
Refactor 2 changes the signature of RESTClient to take a
ClientContentConfig instead of ContentConfig - the primary difference
being that ClientContentConfig uses ClientNegotiator instead of
NegotiatedSerializer and the old Serializers type. We also collapse
some redundancies (like the rate limiter can be created outside the
constructor).
The bug fix is to negotiate the streaming content type on a Watch()
like we do for requests. We stop caching the decoder and simply
resolve it on the request. We also clean up the dynamic client
and remove the extra WatchSpecificVersions() method by providing
a properly wrapped dynamic client.
Not every object kind can be registered via tracker .Add() called as
part of SimpleClientset initialization. This is because .Add() relies
on UnsafeGuessKindToResource to convert object kinds into resource
type names, which is broken for some resources. An example of an
affected kind is NetworkAttachmentDefinitions CRD that uses
network-attachment-definitions as its resource type name. When
UnsafeGuessKindToResource is called for this kind, it returns
networkattachmentdefinitions (without dashes).
As per the comment inside .Add, kinds affected by
UnsafeGuessKindToResource deficiencies should instead register objects
using tracker .Create() method. Problem is, current SimpleClientset
struct definition doesn't expose the object tracker in any way, which
makes it impossible to properly register these kinds at all.
To address the issue, this change modifies the definition of
SimpleClientset struct to expose the object tracker used via Tracker()
method.

Just run using:
`find . -name .import-restrictions | xargs python ~/junk/sanitize-import-boss.py`
The removed entries are either packages that got moved/renamed/deleted
but are still not cleaned up from .import-restrictions files.
