Allow passing system properties in an alternative way

[dschiavu]

Hi,

Would it be possible to allow passing properties such as fake.awsRegion, which are currently passed via JVM system properties, in alternative way, for example via JDBC driver properties?

The reason I'm asking this is because I'm using redshift-fake-driver from Python via the https://pypi.org/project/JayDeBeApi/ Python package (it allows using JDBC drivers from Python), however using it I have no way to pass JVM system properties to it.

Thanks
