Justin Santa Barbara ffb6cd61aa Rolling-update validation harmonization 
This is a follow-on to #8868; I believe the intent of that was to
expose the option to do more (or fewer) retries.

We previously had a single retry to prevent flapping; this basically
unifies the previous behaviour with the idea of making it
configurable.

* validate-count=0 effectively turns off validation.

* validate-count=1 will do a single validation, without flapping
  detection.

* validate-count>=2 will require N succesful validations in a row,
waiting ValidateSuccessDuration in between.

A nice side-effect of this is that the tests now explicitly specify
ValidateCount=1 instead of setting ValidateSuccessDuration=0, which
had the side effect of doing the equivalent to ValidateCount=1.

Justin Santa Barbara 31bb16d4d1 Add context.Context to most signatures 
The client-go signature for most methods adds a context.Context
object, and also makes Options mandatory.  Feed through a
context.Context through many of our methods (but use context.TODO to
stop it getting totally out of hand!)

Peter Rifel 3dc06afa12 Fix goimports errors 
It turns out we werent running verify-goimports in our CI jobs.

While we work to get that enabled, we can at least unblock the releases by doing a one-time fix of the failing goimports

Change code from glog to klog 
We don't call klog.InitFlags yet, because that will cause a flag
redefinition error until we get everyone to stop using glog.  That
will happen when we update to k8s 1.13.

Justin Santa Barbara eec1141a41 Rationalize timeouts for rolling-update 
The intervals remain the minimum time between instances; drain &
validate time is additional.
