Update ansible to 2.5.2

[pyup-bot]

This PR updates ansible from 2.4.3.0 to 2.5.2.

Changelog

2.5

[Porting Guide](https://docs.ansible.com/ansible/devel/porting_guides/porting_guide_2.5.html)

Major Changes
* Removed the previously deprecated 'accelerate' mode and all associated keywords and code.
* New simpler and more intuitive 'loop' keyword for task loops. The ``with_<lookup>`` loops will be deprecated in the near future and eventually removed.
* Added fact namespacing, from now on facts will be available under `ansible_facts` namespace (i.e. `ansible_facts.os_distribution`) w/o the `ansible_` prefix.
They will continue to be added into the main namespace directly, but now with a configuration toggle to enable this,
currently on by default, in the future it will be off.
* Add a configuration file to filter modules that a site administrator wants to exclude from being used.
