Migrate to new Titan CC records

Implements #1 (closed) for the use case applications. Closes #34 (closed)

• Applications use the new Avro records instead of Kieker records
• UC1 Workload generator sends Avro records

Depends on !6 (merged) to be merged. Either !6 (merged) implements sending the Avro records or after it was merged, the avro sending is implemented in this Merge Request.
