In some rare cases, we hit an NPR because the k8s code tries to use the
ctx we are not passing.

aws: Graceful handling of EC2 detach errors
Sometimes, we observe the following error during a rolling update:

error detaching instance "i-XXXX", node "ip-10-X-X-X.ec2.internal": error detaching instance "i-XXXX": ValidationError: The instance i-XXXX is not part of Auto Scaling group XXXXX

The sequence of events that lead to this problem is the following:

- A new ASG object is being built from the launch template
- Existing instances are being added to it
- An existing instance is being ignored because it's already terminating
W0205 08:01:32.593377     191 aws_cloud.go:791] ignoring instance as it is terminating: i-XXXX in autoscaling group: XXXX
- Due to maxSurge, the terminating instance is trying to be detached
  from the autoscaling group and fails.

As such, in case of EC@ ASG deatch failures we can simply try to detach
the next node instead of aborting the whole update operation.

Bharath Vedartham 7067f5f47a instancegroups: Ignore validation errors in unrelated instance groups
When unrelated instance groups produce validation errors, the instance group
being updated produces a failure and is forced to wait for rolling update to continue.

This can be avoided as failures in different node instance groups usually don't affect
the instance group being affected in any way.

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!)
