* Adjust DispatcherProvider interface to return type `CoroutineContext`.
This is a preamble to fix a few coroutine tests that require time advancement.
We need to be able to pass the TestCoroutineScope's context to classes under test.
This can now be done using CoroutineContext.asDispatcherProvider().

* Fix compile error in test

* 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)

to determine an accurate time offset.

"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).

* Add unit test for Gson ByteArrayAdapter.

but for this it's better to read it in one block vs jumping to extra methods.

* More linting issues, adjusting project code style prevent a few of these in the future.

* Added missing unit tests for `KeyFileDownloader` and fixed faulty behavior that was noticed during testing.

* CRUD (instrumentation) test for `KeyCacheDatabase`

* 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.
