Fixes #11852

Fixes #11851

Fixes bugs related to creating Templar() objects on the fly, where
the shared loader objects (serialized to TaskExecutor) aren't used
so information loaded into plugin loaders after forking is lost.

Fixes #11815

This field is templated specially during the TaskExecutor's loop
calculation, so there's no need to post validate it again.

Make 'pause: prompt=…' print the prompt

In stable-1.9, the prompt string is passed to raw_input(), which prints
it without an extra \n. Here we're just print()ing it, so the \n would
be doubled.

Without at least one worker process, things break:

Traceback (most recent call last):
  File "/home/ams/extern/ansible/ansible/lib/ansible/executor/process/result.py", line 103, in run
    result = self._read_worker_result()
  File "/home/ams/extern/ansible/ansible/lib/ansible/executor/process/result.py", line 69, in _read_worker_result
    (worker_prc, main_q, rslt_q) = self._workers[self._cur_worker]
IndexError: list index out of range

Remove TODO: the play already overrides options

Show a better message when ansible.cfg is not found

Earlier we would say «Using  as config file» if we didn't find one.
