Title: Add pam_limits module to ansible : modify PAM limits for Linux

I coded a pam_limits ansible module to modify the /etc/security/limits.conf file, for Linux. It's common to all linux distros.
If rule is absent, it's added to file
If rule is present, it's modified
use_max and use_min permits to take min or max value between the old or new value.
