Introduce new Benchmark class and Patcher

This MR covers most of #151 (closed)

In detail, it includes:

• Introduction of the new benchmark and patcher types defined in #151 (closed), closes #142 (closed)
• Refactoring of many components, e.g. the K8s manager according to #151 (closed), closes #143 (closed)
• Allow setting arbitrary environment parameters, close mostly #98 (closed)
• Load configuration based on two YAML files, this closes the first part of #137 (closed)
• Allow to set Kafka and Zookeeper service names, closes #122 (closed)
• Usage of the new Workload Generator, closes #157 (closed)

TODOs before ready to merge:

• Remove hard coded parts, e.g. type of instances and loads, which is not actually loaded by configuration, see Resource and LoadDimension class in kotlin.
• Change ("patching") methods from the Kubernetes managers to actual patchers to fully resolve #143 (closed)
• Test everything inside Kubernetes.
• Clean up, remove old classes and benchmark types
• Add a NodeSelector Patcher to resolve #93 (closed)
• Maybe we need more Patchers to fully resolve #98 (closed), if more of the non environment parameters (such as K8s ResourceLimits, K8s Labels, ..) must be configurable (@she ?)
• Make namespace configurable moved to #155 (closed)
