Just an FYI: This PR is to simply change "control_path =
~/.ssh/ansible-ssh-%%C"(in ../amazon-ec2/ansible.cfg) to "control_path =
~/.ssh/ansbile-ssh-%%h-%%r" to allow linux systems to deploy to EC2. When I
tested the change with Mac it didn't throw any errors at the same point for
""TASK [setup] ***"---
