Abhijit Menon-Sen 565c6f1ae7 Make ansible_pipelining a connection variable
SSH pipelining can be a significant performance improvement, but it will
not work if sudoers is configured to requiretty. With this change, one
could have pipelining enabled in ansible.cfg, but use sudo to turn off
requiretty in a separate play (or task) where pipelining is disabled:

    - hosts: foo
      vars:
          ansible_pipelining: no
      tasks:
        - lineinfile: dest=/etc/sudoers line='Defaults requiretty' state=absent
          sudo_user: root

(Note that sudoers has a complicated syntax, so the above lineinfile
invocation may be too simplistic for production use; but the point is
that a separate play can do something to disable requiretty.)
