Add benchmark implementations for Hazelcast Jet

Succeeds !150 (closed) and closes #234 (closed).

Open points are:

• Fix open PMD warnings
• Build and push container images in CI pipeline (see !187 (merged)) (for @she)
• Add (updated) Benchmark definitions
• Necessary adjustment for monitoring the lag
• Testing
• Issue reported in 16de8bb5 (comment 10376)
  • The link generated by GitLab seems not to work. The corresponding file/line is 16de8bb5 with comment by @stu208458:

    Throws an exception when trying to run a jUnit test. Cause unknown. Might be caused by:

    • Wrong configuration of test pipeline/test inputs/etc.
    • Multiple test inputs not supportet
