Enabling SSH pipelining by default in Ansible

By Abhijit Menon-Sen <ams@toroid.org>


While writing about ansible_ssh_pipelining earlier, it occurred to me that pipelining could be made to work with requiretty, thus saving having to edit /etc/sudoers, and even making it possible to use su (which always requires a tty). This would mean pipelining could be enabled by default, for a noticeable performance boost.

Here's a working implementation (see the commit message for gory details) that I've submitted as a PR for Ansible 2. Let's hope it's merged soon.
