Fortios file only mode + integration tests (#23275)

* WIP file_mode

* WIP

* Add file_mode + integration tests

* fix pep8

* Update doc fragments
Create mutualy_exclusive param
Fix yamllint problem in tests

* Add aliases file + main playbook for fortios

* Install pyfg before running tests

* Install pyfg before running tests in role

* Remove pre_task as it's done in roles

* Force pyFG minimal version for python3

* role_path not role_dir :(

* Change requirements

* Specify Error type when error on import

* Bug in pygf library with python 2.5 (PR is waiting https://github.com/spotify/pyfg/pull/19)

* Bad requirement format

* still bad format -_-'

* remove test/integration/fortios.py (auto generated by tests)
missing new lines at end of file

* pyFG is now fixed in 0.50
