-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

Due to the merge the project was not possible to build with gradle.
Because both projects changed the gradle build file some properties
were not added to the correct places in the file.
Further in one configuration class the same property existed twice.

Replace the kieker records with the avro records in uc3 application.

In order to not add a new configuration key that is needed by
all the kafka stream use case applications extract the configuration
keys to the kafkastreams common project.

Replace the kieker records with the avro records in uc2 application.

The Project is renamed to theodolite and therefore all packages
should be renamed likewise.

Add the spesb prefix to all self implemented java packages of the
project. Because this changes the fully qualified class name of
the main classes the build.gradle files need to adopt to this.
