LINUX / System Roles: Suggestion of less invasive system role

[benblasco]

The timesync system role would be a good example to demonstrate, with suggested vars to enter into the template:

system_roles:
  - timesync

timesync_ntp_servers:
  - hostname: au.pool.ntp.org
    pool: yes
    iburst: yes

This could be added as a second example in the suggested usage at: https://github.com/RedHatGov/product-demos/blob/main/linux/README.md

Great idea. The variables need to be updated here
