The load of the program arguments are moved to the main function
call and the rest is extracted into a main function, that get
the needed arguments passed.

Use the parameters -res and -reso to reset the kubernetes cluster.
With -reso only the cluster is resetted in nothing else is executed.
With -res the cluster gets resetted before execution of the usecase.

The order of the environment variables is atm crucial for the
run uc py.

Run uc py still used statefullSet instead of deployment

Fix #70

-Use aggregation from titan with dataflow
-Add an aggregation-feedback topic
-Enable logging in UC2 with new slf4j version
-Use newer Kafkastreams version
-Remove unused ConfigurationKeys class

Because of suppress and a compute intensive log in the stream
application the use case may not produce any output.
Further a log message is added for every computed aggregation.
