Cannot delete tests older than 21 days - DE: Tests die älter als 21 Tage sind, können nicht gelöscht werden (EXPOSUREAPP-2398) (#1586)

* 1. Replaced redundant uiStateState during test result fetch with a NetworkRequestWrapper that is able to represent multiple states. This allows for better request state handling throughout the app
2. Completely removed the SubmissionViewModel
3. Failure to fetch the test should now always display the invalid test card on the home screen

* Enable logfile for tester builds by default.

* Fix test regression.

* Make config sharing behavior `SharingStarted.Lazily`. (start once, never release)
Otherwise classes that are just interested in the current config, if there is no other subscriber active,
would launch the `startValueProvider` and pull a config each time.

The ExposureDetectionTracker is such a candidate that would like to use the latest config every ~3min.

While this already no longer happens since "Track config changes" (4d1ecb54),
because there is no a class that is permanently subscribed to `currentConfig`, we should not rely on side-effects,
so let's make the sharing behavior explicit.

* Fix test regression.

GSON deserializes this into a null object that looks like a non-null object until it is evaluated some time later.

Force an evaluation via `require(it.size >= 0)` and delete the corrupt data file when catching the exception.

* Show a visible error dialog if we fail to save data.

There is a number of place in the app with the following code pattern:

try {
    // do some suspending operation
} catch(e: Exception) {
    e.report(ExceptionCategory.EXPOSURENOTIFICATION) // or similar
}

In all such place if the corresponding suspending gets cancelled for any reason, the resulting CancellationException will get reported as an application crash. This fix prevents it from happening, since a cancellation exception is a part of a normal operation, not a failure that should be reported.

* Implemented exposure window provider, adjusted ENF Client

* Implemented new provideDiagnosisKeys to activate ExposureWindow mode, deprecated old diagnosis related content

* Adjusted ENFClientTest

* conflict fix - wip

* test fix

* Split and hide the protobuf config behind interfaces with individual mappers responsible for creating the desired formats.

* Merge branch 'release/1.7.x' into feature/3455-more-frequent-riskscore-updates-configs

* Sync tools need to tell what (if) new packages have been downloaded.

* Interval checks for exposure detection.

* Use the ENFClient, avoid direct access to the calculation tracker.

* Remove defensive check "wanted countries"/"available countries" to reduce server hits.

* CalculationTracker's timeout should come from the AppConfig (androidExposureDetectionParameters.overallTimeoutInSeconds)

* Add test to confirm that we delete stale locations.

* Finished key packages test screen.
Introduced some boilerplate code to make async diffutils easier to use (will help us with the homefragment later on).

* Check valid max and min config values.

* Fix linting issues.

* Address PR comments.

It's now also part of the `TestSettings` and the connection state is faked for the `NetworkStateProvider` class which may be reused.
