----------------------------------------
NicoK opened a new pull request #6470: [FLINK-10006][network] improve logging
in BarrierBuffer: prepend owning task name
URL: https://github.com/apache/flink/pull/6470
## What is the purpose of the change
Almost all log messages of `BarrierBuffer` do not contain the task name and
are therefore of little use if either multiple slots are executed on a single
TM or multiple checkpoints run in parallel.
Please also merge to `release-1.6` and `master`.
## Brief change log
- prepend the owning task name to `BarrierBuffer` log messages (available
from the `InputGate`)
- add task name to `SingleInputGate` logs
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.
- Tested manually the log messages with logging level set to `DEBUG` and the
`SocketWindowWordCount` with checkpointing and parallelism 4.

- Dependencies (does it add or upgrade a dependency): **no**
