* Rewrite the backend manager. This creates a new more logic backend manager that handles all backend operations. For each top-level operation, there is now a single backend manager instance that is passed to sub-commands. The internals of the backend manager are now rewritten to use async logic instead of threading. The design uses a single task runner that dispatches operations and honors concurrent settings and limits from one place. The logic for each operation has been moved into a separate files/classes to make it easier to understand each operation. This fixes #5804 * Fixed a few issues with not awaiting tasks * Fixed not creating empty databases * Fixed an issue with hashes not being recorded on download * Reworked the download logic to avoid attempting to decrypt the file if it has been modified. * Review fixes * Renamed db collector to better reflect the purpose. * Review fixes
