    CentOS lockout user after 5 consecutive failed login

    Current pam configuration allows user to login with correct
    password right after 5 consecutive failed attempts. This change
    updated pam configuration to ensure a lockout of the user for
    5 mins after the 5 failed login.

    Test Plan on CentOS:
    PASS: OS user lockout for 5 mins after 5 failed login attempts on
          console.
    PASS: OS user lockout for 5 mins after 5 failed login attempts on
          ssh.
    PASS: ldap user lockout for 5 mins after 5 failed login attempts on
          console.
    PASS: ldap user lockout for 5 mins after 5 failed login attempts on
          ssh.
