[FLINK-8221][network-benchmarks] Define latency network benchmarks in Flink
project
## What is the purpose of the change
This PR is based on #5134 and adds tools to setup simple micro-benchmarks
for verifying the latency of the network stack. It also adds one latency
benchmark itself.
## Brief change log
- add latency micro-benchmark tools in `StreamNetworkPointToPointBenchmark`
- add a simple point-to-point latency benchmark in
`StreamNetworkPointToPointBenchmarkTest`
## Verifying this change
The defined benchmarks can be run manually and are auto-executed by
flink-benchmarks (dataArtisans/flink-benchmarks#3).
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): **no**
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: **no**
- The serializers: **no**
- The runtime per-record code paths (performance sensitive): **no**
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: **no**
- The S3 file system connector: **no**
## Documentation
- Does this pull request introduce a new feature? **no**
- If yes, how is the feature documented? **not applicable**

[FLINK-8178][network] Introduce not threadsafe write only BufferBuilder
While Buffer class is used in multithreaded context it requires
synchronisation.
Previously it was miss-leading and unclear, suggesting that
RecordSerializer should
take into account synchronisation of the Buffer that's holding. With
NotThreadSafe
BufferBuilder there is now clear separation between single-threaded
writing/creating
a BufferBuilder and multithreaded Buffer handling/retaining/recycling.
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.
