[promtail helm chart] - Expand promtail syslog svc to support values (#1731)

* Expand promtail syslog svc to support values

The promtail helm chart syslog service configuration in the values.yaml
supports elements not accounted-for in the actual syslog service
template.

This change modifys the promtail syslog service to account for those
missing elements.
