Make interprocess polling interval configurable (#16560)

Browse source 
As recently there was back-and-forth with this hardcoded value
(0.001 -> 0.01 -> 0.005), obviousely the optimal value for it depends on
Ansible usage scanario and is better to be configurable.

This patch adds a new config option in DEFAULT section,
`internal_poll_interval`, with default of 0.001 corresponding to the
value hardcoded in Ansible v2.1.
This config option is then used instead of hardcoded values where
needed.

======================
.. versionadded:: 2.2
This sets the interval (in seconds) of Ansible internal processes polling each other.
Lower values improve performance with large playbooks at the expense of extra CPU load.
Higher values are more suitable for Ansible usage in automation scenarios, when UI responsiveness is not required but CPU usage might be a concern.
Default corresponds to the value hardcoded in Ansible ≤ 2.1::
internal_poll_interval=0.001
