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

Signed-off-by: Kolya Opahle <k.opahle@sap.com>

* Keep displaying fetching card on server errors as this usually does not indicate any problems with the test itself

* Replaced KeyFileDownloader.kt in favor of KeyFileSyncTool.kt.
Supports new logic for more frequent downloads
First draft.

* Change "country" to location, which is more fitting.

* Split sync success tracking into days and hours, track them separately.

* Fix stale location data not being cleaned up.

* Test fragment, first drafts.
Remove 24 hour mode options, no longer used.

* Implemented metered connection check for hourly key download.

* Provide timeout values for download transaction and individual downloads via app config.

* Complete unit tests for FlowPreference and DownloadConfigMapper-

* Unit tests for day and hour sync tool.

* Complete tests for KeyPackageSyncTool.kt

* klint & detekt <3

* Fix tags and commented out code (the deletion behavior is covered by `getting completed keys`

* Fix text typo.

* 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).

* Remove ETag fallback behavior, missing ETag is such an edge case that we should throw.

* Check valid max and min config values.

* Fix linting issues.

* Address PR comments.

* EXPECT_NEW_*_PACKAGES should be based on the package time data, not the download creation timestamp.
The downloads creation timestamp can be subject to race conditions.

* Fix overflow due to time addition with Long.MAX_VALUE

* Clean up tests

* Don't crash the task if we can't get today's hour index.
(Makes timetravel testing difficult, and a real abort reason would be a crash on the day index)

* Display errors (don't crash) when running manual keysync from the test menu.

* Rename `forceSync` to `forceIndexLookup`.

* Remove outdated comments.

* Spell out viewholder.

* Move `maxExposureDetectionsPerUTCDay == 0` into it's own check.

* Change test menu metered connection button behavior. It's now a button that "fakes" the connection status to metered.
It's now also part of the `TestSettings` and the connection state is faked for the `NetworkStateProvider` class which may be reused.

* Change test menu metered connection button behavior. It's now a button that "fakes" the connection status to metered.
It's now also part of the `TestSettings` and the connection state is faked for the `NetworkStateProvider` class which may be reused.

The app config alone determines which locations we try to sync.

* Add default app config as last resort fallback.

* Change config type names and improve logging for HotDataFlow.kt

* Run the app config retrieval on the app scope, otherwise UI unsubscription could cancel the app config retrieval.

* Offer "identifier" property that can identify app configs such that subscribers know when it is considered changed.

* Behavior change AppConfigProvider.kt, there is no caching/replay grace period, once the last subscription is gone, it's  last value is cleared.

* Klint ;)

* Add a unit test specifically for checking the default configs checkum and parsability.

* Make the AppConfig observable.
Provide the server time offset.
Offer a lastUpdatedAt timestamp.
Add an app config specific test screen.
Clean up test screens a bit and move debug options out of API test options.

* Fix test regression due to refactoring (moved code around).

* Store the server timestamp and offset at retrieval.
Switch to config storage via json to be able to store additional meta data fields (i.e. time).

* KLint and Me have a hate relationship based on both mutual admiration.

* Fix time offset parsing being locale dependent.

* Fix broken unit tests.

* Improve offset accuracy, move before unzipping.

* Fix overly long livedata subscription to results (viewmodel scope vs observer scope)

* Add mapping for the new protobuf configs + tests.

"AppConfigProvider" is now only responsible for making it available.

* Simplify current concepts for making the app config observable until we have a default configuration.

* Improve app config test screen, delete options, better feedback.
Show toast instead of crash on errors.

* Fixed GSON serialization not encoding/decoding the byte array correctly.
Added specific type adapters for instant and duration to get cleaner json.

* Remove type adapters from base gson due to conflict with CalculationTrackerStorage.

* We want to default to forced serialization of instant by our converters, instead of using the default serialization which will differ
between Java8.Instant and JodaTime.Instant, to prevent future headaches there, register explicit converters by default,
and overwrite them if necessary (currently only needed for CalculationTrackerStorage.kt).

* Improve AppConfigServer code readability by moving code into extensions.

* Fix merge conflicts

* Throw a more specific exception if gson type decoding fails due to malformed base64 encoding.

* Add unit test for Gson ByteArrayAdapter.

* Remove unused `FileStorageHelper` and related constants+tests.

* Fix last3Hours unit test in deviceRelease mode, we need to explicitly enable debug for these tests.

* Until we have more information about the hashsum's format in the header, default to `ETag

* Split app config server API from diagnosis key download API,
and reintroduce caching for the app config download.

* Add test to check that the cache is used on flaky connections.

* Code changes based on PR comment, part #1.

* Code fluff, formatting.

* Handle download errors correctly.

* Refactoring:
* Remove unnecessary `currentDate` we always start with the newest date from the servers index.
* Make a specialised class for header validation

* Let legacy cache migration abort early, depending on whether the key dir exists.

* If we can't create the base directory for the key repo, throw an exception.

* Delete cache entry if a download fails.

* Fixed test regression due to refactoring.

* Consolidate staleness check into `getStale`

* Consolidate clean up for failed downloads into the download method.
Added tests to check that we delete the keycache entry if the download fails (which we didn't for hours :O!)

* Because the hour-mode uses caching too, we add an explicit button to the test menu that clears the cache.

* Add comment with reference to ticket regarding follow up on the other headers.

* Move expected storage size per country into a named constant.
