Change to pam_faillock and pam pwquality

pam_tally2 is being replaced by pam_faillock. The parameters in
common-auth have moved to faillock.conf, so this commit adds a new
method to modify paramters in a given configuration file.

The output from the 'faillock' command differs from 'pam_tally2', so
this commit adds a new function to parse the output from 'faillock' to
determine if the user is currently locked.

pam_cracklib is being replaced by pam_pwquality. The parameters in
common-password have moved to pwquality.conf.

I referenced the work done by Joseph Reynolds in this commit [1] to know
what changes were required.

Tested:
Confirmed that the AccountLockoutDuration and AccountLockoutThreshold
parameters under /redfish/v1/AccountService both return the correct
value from common-auth.

Set deny to 10 and unlock_time to 30 seconds and confirmed that a user
account will correctly show as locked after 10 failed login attempts,
and that user will show as unlocked 30 seconds later.

Used Redfish to PATCH both AccountLockoutDuration and
AccountLockoutThreshold and confirmed that the updated values are
correctly reported in Redfish and that the correct lines in
faillock.conf are modified.

Confirmed that the MinPasswordLength parameter under
/redfish/v1/AccountService returns the correct value from
common-password.

Set minlen to 9 and confirmed that a user password could not be set with
a length of 8.

Used Redfish to PATCH MinPasswordLength and confirmed that the updated
value is correctly reported in Redfish and that the correct line in
pwquality.conf is modified.
