ansible.cfg: improve ssh ControlPath
AWS hosts and user names frequently make the default Ansible ControlPath too long. This prevents ssh persistent connections, significantly impacting runtime. More detail: https://github.com/ansible/ansible/issues/11536 This config change shortens the ControlPath to make this less likely. It would be better to change it to the %C hash, as extremely long hostnames or usernames could still encounter this problem, but that is not yet available with RHEL's openssh. This at least improves the situation.
