CentOS 8.x Configure password complexity

To configure password complexity in CentOS 8 use:

Install required packages
```
dnf -y install authselect-compat
```
Create authselect profile based on sssd for configuring password-complexity
```
authselect create-profile sssd-prod1 -b sssd
```
This creates new authentication profile at '/etc/authselect/custom/sssd-prod1'
List the profiles with
```
authselect list
```
See current profile with
```
authselect current
```
Select the new profile using:
```
authselect select custom/sssd-prod1
```
Configure password complexity using:
```
authconfig --enablereqlower --enablerequpper --enablereqdigit --enablereqother --passminlen=8 --passmaxrepeat=3 --update
```
This ensures that various files in /etc/pam.d require use of pam_pwquality.so. This also updates /etc/security/pwquality.conf.d/10-authconfig-pwquality.conf with required password complexity configuration.
