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.
