Command line options override config files like ansible.cfg, but
not inventory data or playbook directives. This allows us to over-
ride remote_user with `-u` on the command line to log in as root
before we have set up the provisioning user.

This reverts commit 4f357f336f.
On a hunch I recreated my Ansible virtualenv using Python 2.7 and now
connections work properly again without this. Something seems to have
happened with Python 3 in Ansible > 2.4.0.0.
For reference, Python version was 3.6.3 when it was not working, and
now it is working with Python 2.7.14.
Not sure what causes it but I get timeouts when connecting to my hosts
with Ansible > 2.4.0.0 (tested 2.4.1.0 and current 2.5.0-devel). For
some reason switching to paramiko fixes it.
Pipelining makes ansible run tasks much faster, and as of Ansible
2.0 or 2.1 or so, it now works on older hosts that have requiretty
in their sudo config[0]. Also, disable the creation of those stupid
retry files.
