sample-controller: add status subresource support

Browse Source 
- Add an example to show how to use status subresources
with custom resources.
- Update the comment in the controller to mention that
`UpdateStatus` can now be used.
- Generate `UpdateStatus` for Foo.
- Update the README to remove feature gate information for
CRD validation since the current example requires a v1.9
cluster and it is enabled by default.
- Update the README to add feature gate information for
CustomResourceSubResources.
