* Simplified task control by having all logic in a single class and using async control mechanism
* Fixed the tests
* Made the marking of a backup partial explicitly communicated if the enumeration process is stopped.
* Added support for pausing active transfers
* Introduced transfer token to abort operations.
* Updated the way LiveControl is emitting events.
* Retains the paused state of the server across reboots, this fixes#5760.
* Reworked the way throttle speeds are propagated through LiveControls.
* Added option to pause transfers in the UI.
* Removed throttle settings from the LiveControls class so it is exclusively handled by the ApplicationSettings.
* Removed `thread-priority` as it does not work at all when tasks are used.
* Fixed the stop dialog and API to only support stop and abort.
* Removed unused variables
In code the throttling generally works backwards than what one would expect.
The streams that are throttled are the streams that operate on files from the local machine.
This fixes the download throttling not working and the upload throttling applying to
both uploads and downloads.
When doing a Put operation the stream on the local machine is reading from the
local filesystem and hence the upload throttle bytes per second needs to be
applied to the reading of the stream, not the writing.
Similarly when doing a Get operation the download throttle bytes per second needs
to be applied to the writing of the stream.
Fixes#4115
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.
A method marked async that does not use await will run synchronously.
By removing the async modifiers, we make it more explicit that these are
synchronous methods. This also addresses some compiler warnings, and
avoids the creation of the state machine used to handle asynchronous
operations.

Changed a few things on the way, removing the log process
