…s unready. Deprecated LongNotStarted

 In cases where node n1 would:
 1) Be created at t=0min
 2) Ready condition is true at t=2.5min
 3) Not ready taint is removed at t=3min
 the ready node is counted as unready

 Tested cases after fix:
 1) Case described above
 2) Nodes not starting even after 15mins still
 treated as unready
 3) Nodes created long ago that suddenly become unready are
 counted as unready.

The backport included unit tests using a function that changed signature

* Fix cluster-autoscaler clusterapi sample manifest

This commit fixes sample manifest of cluster-autoscaler clusterapi
provider.

(cherry picked from commit a5fee21)

* Adding functionality to cordon the node before destroying it. This helps load balancer to remove the node from healthy hosts (ALB does have this support).
This won't fix the issue of 502 completely as there is some time node has to live even after cordoning as to serve In-Flight request but load balancer can be configured to remove Cordon nodes from healthy host list.
This feature is enabled by cordon-node-before-terminating flag with default value as false to retain existing behavior.

* Set maxAsgNamesPerDescribe to the new maximum value

While this was previously effectively limited to 50, `DescribeAutoScalingGroups` now supports
fetching 100 ASG per calls on all regions, matching what's documented:
https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeAutoScalingGroups.html
```
     AutoScalingGroupNames.member.N
       The names of the Auto Scaling groups.
       By default, you can only specify up to 50 names.
       You can optionally increase this limit using the MaxRecords parameter.
     MaxRecords
       The maximum number of items to return with this call.
       The default value is 50 and the maximum value is 100.
```

Doubling this halves API calls on large clusters, which should help to prevent throttling.

* Break out unmarshal from GenerateEC2InstanceTypes

Refactor to allow for optimisation

* Optimise GenerateEC2InstanceTypes unmarshal memory usage

The pricing json for us-east-1 is currently 129MB. Currently fetching
this into memory and parsing results in a large memory footprint on
startup, and can lead to the autoscaler being OOMKilled.

Change the ReadAll/Unmarshal logic to a stream decoder to significantly
reduce the memory use.

* use aws sdk to find region

* update readme

* Update cluster-autoscaler/cloudprovider/aws/README.md
