Add an annotation that can be added to the exampleType passed to
NewReflector to indicate the expected type for the Reflector. This is
useful for types such as unstuctured.Unstructured, which, when used with
a dynamic informer, do not have their TypeMeta filled in.

All other clients:
- expose a New() method that takes a rest.Interface
- expose their RESTClient()
- return pointers to the type, not instances of an interface that the
type implements
For code that is generic over all Kubernetes clients, and for general
developer experience, it's best to make sure that this client adheres to
these common practices.

With the introduction of GVK to the fake dynamic client it made using
the fake much more cumbersome.
Specifically:
- requires manual registration of list types
- mismatch between scheme types and passed in fixtures would result in errors
The PR changes the constructor method NewSimpleDynamicClient to do the following:
- rewire the schemes to unstructured types
- typed fixtures are converted to unstructured types
- automatically register fixture gvks with the scheme
This should make the dynamic client 'flexible' with it's inputs like it was
before

Today the dynamic fake client is not aware of *List kinds, so List calls return UnstructuredList
objects without TypeMeta. This patch updates client-go's fake object tracker to store a map of
GVR to list GVKs. In this way, the list GVK can be set for UnstructuredList objects.

The fake clientset used a slice to store each kind of objects, it's
quite slow to init the clientset with massive objects because it checked
existence of an object by traversing all objects before adding it, which
leads to O(n^2) time complexity. Also, the Create, Update, Get, Delete
methods needs to traverse all objects, which affects the time statistic
of code that calls them.
This patch changed to use a map to store each kind of objects, reduced
the time complexity of initializing clientset to O(n) and the Create,
Update, Get, Delete to O(1).
For example:
Before this patch, it took ~29s to init a clientset with 30000 Pods,
and 2~4ms to create and get an Pod.
After this patch, it took ~50ms to init a clientset with 30000 Pods,
and tens of µs to create and get an Pod.

By correctly handling content type negotiation, we can avoid the
need for a special version of watch and use the same code path as
typed clients.

There was no reason to have two types and this avoids ~10% of allocations
on the GET code path.

The Create, Delete, Get, Patch, Update and UpdateStatus
methods in the dynamic client all expect the name
parameter to be non-empty, but did not validate this
requirement, which could lead to a panic. Add explicit
checks to these methods.

Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`
