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

d014405e1f FIX: add becho to send batch output to syslog too

aa3983c6d0 FIX: add way of completely skipping test that bugged with jessie
Tests are stored in a bash indexed array.
Bash on debian8 does not support arrays declaration and if there was no
registered tests, the array variable was seen as undefined.
With this way of completely dismissing the test suite, the problem is
fixed

71b70a2b8c FEAT: Add sudo_wrapper to catch unauthorized sudo commands
As for now, if a sudo command was not allowed, check might sometimes
pass, resulting compliant state even if it actually is not.
Sudo wrapper first checks wether command is allowed before running it,
otherwise issues a crit message, setting check as not compliant

Fix script to make sudo_wrapper work, split "find" lines
Fix quotes in $@ and $* when running sudo command

Fixed quotes and curly braces with shellcheck report

176fb96fa4 FEAT: automate shellcheck test with docker
IMP: search for all .sh files to shellcheck

.sh files

Fix dockerfile location and expand full shellcheck options

c51a8ee9b8 FIX: sed that was too greedy
Used to sed 's!/usr/bin/su!!' /usr/bin/sudo leaving only "do"
that lead to misinterpreting result

Change algorithm to avoid partial sed in the result list
Now the not compliant list is built out of the find results
instead of items being removed from them.
Allow better control of grep inside this list.

Chore: apply shellcheck recommendations
