Dependency io.debezium:debezium-testing-testcontainers affects logback in tests

Using `io.debezium:debezium-testing-testcontainers:2.2.1.Final` causes a logback-test.xml file to be picked up from the classpath as it depdends on `io.debezium:debezium-core:2.2.1.Final:test-jar`

Example log lines from using `io.debezium:debezium-testing-testcontainers:2.2.1.Final`

Proposed solutions:
1. Exclude the logback-test.xml from being included in the generated test jar
2. Remove the dependency on `io.debezium:debezium-core` test-jar by either duplicating the one class that's required or moving it to src/main/java and depending on `io.debezium:debezium-core:2.2.1.Final:`
