Add support for capturing stdout associated with job events and ad hoc command events.

* New event types for stdout lines not associated with a callback event.
* New stdout, start_line, end_line and verbosity fields for job/ahc events.
* Callback plugins to wrap Ansible default/minimal stdout callbacks and embed callback event data using ANSI escape sequences.
* Callback plugin library to wrap ansible.display.Display class methods.
* Output filter to extract event data from stdout and create job/ahc events.
* Update stdout formats to strip new ANSI escape sequences.
