Use pmon to restart sssd service

Using systemctl to directly restart sssd is causing pmond to handle
this scenario as a process failure.
This commit updates the sssd service restart command in puppet files,
to replace "systemctl restart" with "pmon-restart".

Tests performed:

PASS: sssd service is successfully started.
PASS: sssd service status is enabled and active.
PASS: Kill sssd process multiple times and check if it gets restarted
successfully every time.
PASS: Verified ssl_ca install and update with new certificate triggers
successful sssd restart.
PASS: Verified sssd service is restarted by pmon and not by systemctl
when a new domain configuration is added.
PASS: Verify sssd service connects successfully to local openldap server
