[FLINK-8220] Implement set of network benchmarks
This PR implements sets of network benchmarks that are intended to simulate
various workloads for network stack. Benchmarks will be executed by
`flink-benchmarks` project. We want to keep the code of the benchmarks here,
since components they are using are not part of public api and we don't wont
them braking unknowingly on changes in the flink code.
## Verifying this change
This change adds two tests ensuring that benchmarks are compiling and
executing as expected without an exceptions.
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): (yes / **no**)
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: (yes / **no**)
- The serializers: (yes / **no** / don't know)
- The runtime per-record code paths (performance sensitive): (yes /
**no** / don't know)
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know)
- The S3 file system connector: (yes / **no** / don't know)
## Documentation
- Does this pull request introduce a new feature? (yes / **no**)
- If yes, how is the feature documented? (**not applicable** / docs /
JavaDocs / not documented)

[FLINK-8172][network] Write to memorySegment directly in RecordSerializer
This increases throughput of network stack by factor of 2, because
previously
method getMemorySegment() was called twice per record and it is a
synchronized
method on recycleLock, while RecordSerializer is sole owner of the Buffer at
this point, so synchronisation is not needed.
