As part of the parallel upload changes a bug slipped in where a check was
being made if the index volume writer exists before creating said index
volume writer. Fixed by changing the test to check if the temporary index
volume exists and then creating the writer for the index file.
- Rename indexVolume to indexVolumeWriter in DataBlockProcessor to reduce
confusion.
- When flushing the remaining uploads, check the tasks for exceptions in
completion order rather than waiting for them all at once. If there is an
exception all other uploads are cancelled anyway.
- Remove setting the operation progress as Backup_WaitForUpload in the
BackendUploader since the BackupHandler sets it.
- Use an exception filter in BackendUploader.
- Use Options property MaxUploadPrSecond instead of getting the raw value.
Encrypting, hashing, and creating index volumes are now done
in the DataBlockProcessor and the SpillCollectorProcess. This allows
uploads to always be transferring data and not have to stop to create
a file, encrypt data, etc.
Changed a few things on the way, removing the log process

Previously, empty files were associasted with empty blocks. These blocks were added to volumes which could result in empty, but valid volumes being garbage collected and valid file entries deleted.
This change changes the logic so that empty blocks are not stored at all.
