Ticket #48081 - Add regression tests for pwpolicy
    
    Description: When troubleshooting TET test failures for RHEL-7.4, we
    found couple of issues related to PasswordCheckSyntax attribute. One
    of the issue is accepting trivial password and other one is rejecting
    Passwords similar to cn, sn and uid attributes. Automated both the
    bugs in this patch.
