When the code following the await can be executed on any thread, it's
recommended to use ConfigureAwait(false) to avoid unnecessary context
switching and potential deadlocks.
Some changes were required for this merge,
now the StreamBlockSplitter process will take in any stream, store the blocks and return the blockset ID.
This makes it compatible with the changes for metadata handling where they support more than a single block of metadata.
