This commit changes the way aws auth is managed. Before a local file
was used the generate the template and a null resource to apply it. This
is now switched to the terraform kubernetes provider.
* Add Windows support
* Assign eks:kube-proxy-windows group to worker nodes
* Add Instructions for adding Windows Workers at FAQ.md
* Remove unnecessary variables from userdata_windows.tpl
* Update CHANGELOG.md
* Support map users and roles to multiple groups
* Simplify code by rename `user_arn` to `userarn`, `role_arn` to `rolearn`
* Next version should be 6.x because PR this is a breaking change.
* Update example variables.tf
* Change indent to 2
* Fix map-aws-auth.yaml maybe invalid yaml.
* allow creating an IAM role for each worker group
* moved change from 'changed' to 'added'
* create multiple roles not just profiles
* fix config_map_aws_auth generation
* don't duplicate worker-role templating
* specify ARNs for worker groups individually
todo fix aws_auth configmap
* fixed AWS auth
* fix aws_iam_instance_profile.workers name
fix iam_instance_profile fallback
* fix outputs
* fix iam_instance_profile calculation
* hopefully fix aws auth configmap generation
* manually fill out remainder of arn
* remove depends_on in worker_role_arns template file
this was causing resources to be recreated every time
* fmt
* fix typo, move iam_role_id default to defaults map
