Fix descriptions in comment section for 99.* secaudit checks

Remove duplicated legacy services that are already taken care of by vanilla cis

Enable custom configuration of checks in config-file, no more hard coded conf
Add test to disable check if debian version is too old
Add excused IPs while checking "from" field of authorized_keys
Escaping dots in IPs
Manage Kex for different debian versions
Add tests for generic checks and add apply for ssh config
Apply shellcheck recommendations on audit/hardening scripts
Update script to check for allowed IPs only, remove bastion related
Fill `apply` func for ssh config related scripts
Add and update tests scenarii

Disable shellcheck test for external source 1091

As of today, the entire project is not shellcheck compliant, I prefer
disabling the test that warns about not finding external source (that
arent compliant). I will enable it again when the project library will
be shellchecked
https://github.com/koalaman/shellcheck/wiki/SC1091

Refactor password policy check with one check by feature

Previous file will now only look for bad passwords in /etc/shadow
I added two checks that look for the compliant configuration lines in
conf files /etc/logins.defs and /etc/pam.d/common-passwords

FIX: merge chained sed and fix regex

FIX: update regex to capture more output
FIX: fix pattern to ignore commented lines, add apply

Also add tests to ensure that commented lines are not detected as valid
configuration

CHORE: cleanup test situation with file and users removal
IMP: add case insensitive option when looking for patterns in files
CHORE: removed duplicated line in test file
