* 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
The QuotaCheck is done in two places, and only one place was checking if the quota check was supposed to be disabled.
This adds the check in the other place.
The assigned quota size is checked in addition to the reported backend quota (if available). It can be used to limit the backup size on the remote. Warnings are created according to the same quota warning threshold.
Previously, this option had no function.
If set, the backend is treated as if it does not report a quota at all. No warnings and errors are created and no quota values are set in the backup log.
This option is intended to be used if a backend reports a wrong quota, so it needs to be disabled.
Previously, we would catch any Exception thrown by VerifyRemoteList and
perform an auto-cleanup (if specified in the options). However, we
should only perform the auto-cleanup if VerifyRemoteList detected an
issue with the uploaded files. Otherwise, an unrelated exception can
cause the database repair to be performed unnecessarily. In the case of
a connection issue, this can leave the database in a corrupted state.
This fixes#4516.
When a backup is interrupted it will now show as a partial backup in the list of backups on the restore files page.
Temporary filelist volumes are protected from deletion in several places. All but the RestoreHandler
only protect the most recent filelist. The RestoreHandler protects all temporary filelist volumes as the user
might be restoring from one that would be deleted.
Prevent the CoCoL BackendRequests channel is retired exception from appearing when the backup is stopped by checking
if the channel is retired before trying to add the FlushRequest to the channel. Any exceptions from the BackendUploader
task will still be thrown.
Changed a few things on the way, removing the log process

It also makes quota enabled backends return an instance of this interface instead of the quota components separately.
This way, getting quota stats requires only a single remote request on backends like Google Drive and OneDrive.
The Enumerable.Count method will attempt to cast the object to an
ICollection, and if successful, reference the Count property. Since we
know that we have a List, we can reference the Count property directly.
