This PR has a large blast radius because it takes the final step and bumps up the Controller to be fully async.
We have historically done a piece-by-piece update, so all operations were already async but the controller interface was kept synchronous.
With this update, the controller is now fully async and all tests are updated.
Most places where the new C# compiler warns about function names not ending in `Async` were also adressed, giving a massive refactor change.
Functionally, no changes are done.
This PR updates the remove configuration to receive configuration directly on connection, instead of waiting for the server to send it.
This also adds a hibernation setting that will let the server tell the client to stop connecting for a while which can reduce resource consumption at the cost of not being always available.
This PR adds an option to disable control from the console.
With this option it is possible to keep a connection to the console, but not allow remote administration.
This PR adds the ability to manage backup configurations outside of the the client.
The implementation ensures that locally created configurations cannot be affected by the remotely managed backups.
If the instance is not connected to a remote console, this has no effect.
This PR updates the local database to add the column `ExternalID` that tracks backups that are managed remotely.
