[stable-2.9] Change default file permissions so they are not world readable (#70221) (#70825)
* [stable-2.9] Change default file permissions so they are not world readable (#70221)

* Change default file permissions so they are not world readable

CVE-2020-1736

Set the default permissions for files we create with atomic_move() to 0o0660. Track
which files we create that did not exist and warn if the module supports 'mode'
and it was not specified and the module did not call set_mode_if_different(). This allows the user to take action and specify a mode rather than using the defaults.

A code audit is needed to find all instances of modules that call atomic_move()
but do not call set_mode_if_different(). The findings need to be documented in
a changelog since we are not warning. Warning in those instances would be frustrating
to the user since they have no way to change the module code.

- use a set for storing list of created files
- just check the argument spac and params rather than using another property
- improve the warning message to include the default permissions.

CVE-2020-1736

When set_mode_if_different() is called with mode of 'None', ensure we issue
a warning about the change in default permissions.

Add integration tests to ensure the warning works properly.

* Fix tests
- actually use custom module 🤦‍♂️
- verify file permission on created files
- use remote_tmp_dir so we're ready for split controller
- improve test module so we can skip the call to set_fs_attributes_if_different()
- fix tests for CentOS 6

(cherry-picked from commit dc79528cc6)

* Use new category in changelog fragments
