[FLINK-9750] Add new StreamingFileSink with ResumableWriter. ## What is the purpose of the change This PR is the first step towards introducing a new Streaming Filesystem sink that works on top of Flink's filesystem abstraction and provides support for both row and block-based formats (like ORC/Parquet). The current version only supports the LocalFileSystem. ## Brief change log The first commit introduces the new `ResumableWriter` abstraction and an implementation for the `LocalFileSystem`, while the second introduces the new `StreamingFileSink`. ## Verifying this change This changes add tests in the `LocalStreamingFileSinkTest` and the `BucketStateSerializerTest`. ## 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 - If yes, how is the feature documented? not documented yet **NOTE TO REVIEWER**: Still logging is missing.
