Allow timezone to be selected for the logging output (#5)

The timezone for the logger can now be selected using the helm chart
parameter 'timezone'. As logging employs log4j, ensure you use a
Java-friendly timezone ID. Refer to this site for available IDs:
https://docs.oracle.com/middleware/1221/wcs/tag-ref/MISC/TimeZones.html

For example, to use time from Halifax, you would run: 
```
helm install k vertica-charts/kafka-scheduler-chart --set timezone="America/Halifax"
```
