etcd nodes separate from masters in aws

[mbach04]

Currently etcd nodes are staged to be deployed separately in the AWS deployer and should deploy converged with the Masters as recommended by 3.11 architecture documentation.

Removing etcd from the cloud infrastructure definitions in group_vars/all.yaml results in a failed process of the cloudformations template.

Removing etcdnodes from the cloudformations template (casl-ansible/roles/manage-aws-infra/defaults/main.yml) results in AnsibleUndefinedVariable: 'aws_etcd_zones' is undefined.

I'm a bit confused here @mbach04, why are you editing defaults/main.yml file? This is not the way to customise your infra "skeleton". That Ansible dictionary must be configured in your inventory.
