Madhav Jivrajani ffc1b941d4 cacher: Minor cleanup and refactor of code and tests 
* Remove linter warnings.
* Cancel contexts to avoid leaks.
* Rename a few XXXThreadUnsafe to XXXLocked to
  maintain consistency.
  * A few are still called XXXThreadUnsafe mainly
    because those are safe to be called from the
    perspective that only one gorotuine will access
    them - not really called under a lock.

Madhav Jivrajani 4f2ee5cf42 cacher: Use watchCacheInterval to reduce lock contention 
- Modify GetAllEventsSinceThreadUnsafe to return a watchCacheInterval
- Modify Watch() to compute a watchCacheInterval rather than a slice
  of all "initEvents" and pass this interval to process()
- Use interval::Next() to obtain events to process rather than obtain
  them all at once
- Modify tests accordingly to use interval
- On invalidation, stop processing and stop the watch.
- Make indexValidator injectable for testing
- Add unit test for verifying the behaviour of stopping the watch.

Madhav Jivrajani af19f84a96 cacher: refactor process() function 
Split process() function into processEvents() and process().
This is done in anticipation of GetAllEventsSinceThreadUnsafe()
returning an entity using which events can be constructed and
not the events itself.

Subsequently, this commit also moves updating resource version
for initEvents from Watch() to the processEvents() func.

Davanum Srinivas 2710b17b80 Move from glog to klog 
- 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
