justinsb 90cbf75584 Context threading: more wiring 
We're aiming to use this for testing immediately and better
logging/tracing in future, but to make the changes manageable breaking
them into a smaller series that don't directly achieve much.

justinsb 4b2f773748 rolling-update: don't deregister our only apiserver 
If we do, we can't drain the node afterwards.  We also are going to
have dropped connections in this case anyway.

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 1e18a5d344 rollingupdate_test: add tests for rolling update 
The tests create a cluster with 2 node instance groups and 1 master and bastion instance groups.
Only one node instance group requires rolling update.

instanceGroupNodeSpecificErrorClusterValidator mocks a validation failure for a given node group.
rolling update should not fail if the cluster validator reports an error in an unrelated instance group.

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.
