Currently local openldap service (slapd) doesn't have logs at all.
This change enables logging for the service.
Test Plan:
PASS: Verify the logs are generated in /var/log/slapd.log after
system is successfully deployed.
PASS: Verify that standard openldap operations are logged, such as
adding users, searching for users.
PASS: Verify log file is rotated when reaching the configured size.
