aide::config: Add report_ignore_e2fsattrs config parameter.

[olifre]

This allows to ignore selected ext2 file attributes in the
final report. Unset by default.
Very useful to ignore e.g. I (indexed directory)
which on some systems gets flipped automatically
if the number of files in a directory is increased
(example: Log file directories due to rotation).

For more details, see for example this upstream discussion:
aide/aide#47
which considers to ignore e2fsattrs which can not be set or removed.

I'm unsure why the tests fail — is undef not allowed as a default value?

Did you add the unit test for the changes you added? what does pdk test unit show when you run that?

[olifre]

@kekogya Thanks, just learning PDK. I see the issue is caused by the defaults in data/common.yml only applying to aide::init, but the tests instantiate aide::config directly, and the current solution used for other values seems to be to just set all parameters in config_spec.rb.

I'll extend accordingly and add a test for the new feature.

Things should become green now 😄.

Thank you for adding the unit test. I will review the pull request and merge soon.

@olifre pull has been merged. I will be updating the forge module shortly.
