* feat: Officialize Debian 12 support
Functional tests now pass
CIS Benchmark PDF for Debian 12 is not out yet, but the hardening points checked
are still relevant in Debian 12.
OVHcloud is now using it in critical production, hence making it officially supported

Fixes#155
When real entries are present in fstab, system startup or runtime mountpoints are now properly detected
Add a supplementary check in case of partition not present in fstab
Introduce Debian 11 compatibility
Based on CIS_Debian_Linux_11_Benchmark_v1.0.0
After review, here are the notable changes :
- Harden /var/log more (noexec,nodev,nosuid)
- Harden /var/log/audit more (noexec,nodev,nosuid)
- Harden /home more (nosuid)
- Disable cramfs
- Fix 5.3.4_acc_pam_sha512.sh
- Deprecate Debian 9 and remove useless docker images
NB : more audit log rules have been introduced and will be inserted in the checks later
Fix#158
* fix: add filter to hfs
* fix is_kernel_option_enabled check
as the module in question could have dependencies which have been blacklisted as well we need to make sure that the comparison only checks for the module in question - the last line in the output.

Renamed some checks, add new checks that check permissions and ownership on /etc/passwd, /etc/shadow, ...
Add new function in utils that checks that check that the file ownership is one of the authrized ownership.

Shellcheck recommands to replace sed by shell expansions in 'simple' cases.
However, the replacement here is likely to lead to erros, so we disable this rule.
Moreover, it does'nt really add readability.
First one as root to create conf files with good owner and permissions, and then with secaudit.
Now first run with --create-config-files-only and the normally with --audit.
I added two functions in utils that checks perms and ownership for file
resulting for a certain find. It takes parameters to filter the results
if needed.
Add func to find pattern in file that spreads over multiple lines
The func will remove commented lines (that begin with '#')
and consider the file as one long line.
Thus, this is not possible to look for pattern at beginning of line
with this func ('^' and '$')
Improved pattern in 8.2.5
Add syslog-ng to installed dependencies in Dockerfiles
Fixed multifile arguments when looking for pattern that got broken
in d2bbf754 due to "nocase" and _does_pattern_exist_in_file wrapper
Please note that you can only look for pattern in ONE FILE at once
Fixed 8.2.5 and 8.3.2 with for loop on files and 'FOUND' flag
You now need to specify each and every file to look for or embed a
'find' command as follow :
`FILES="$SYSLOG_BASEDIR/syslog-ng.conf $(find $SYSLOG_BASEDIR/conf.d/)"`
Improved test files
Applied shellcheck recommendations
Add function to retrieve actual partition from symlink in lib/utils.sh
Using this func in all 3 audit scripts
Improved tests to test this func
Apply shellcheck recommendations
Trim trailing spaces

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

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
