- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Let the garbage collector use json merge patch when SMP is not supported
**What this PR does / why we need it**:
Let garbage collector fallback to use json merge patch when strategic merge patch returns 415. This enables orphan delete on custom resources.

Enhance the garbage collector to periodically refresh the resources it
monitors (via discovery) to enable custom resource definition GC.
This implementation caches Unstructured structs for any kinds not
covered by a shared informer. The existing meta-only codec only supports
compiled types; an improved codec which supports arbitrary types could
be introduced to optimize caching to store only metadata for all
non-informer types.
This adds an interface form of dynamic.Client and
dynamic.ResourceClient, making those two follow the general client
conventions: `Interface` is an interface, and `Client` is the concrete
implementation. `ClientPool` retains it's interface status.
This allows us to create a fake implemenation of dyanmic.Interface,
dynamic.ResourceInterface, and dynamic.ClientPool for testing.
Allow the list of resources the garbage collector controller should
ignore to be customizable, so downstream integrators can add their own
resources to the list, if necessary.
