* Adopt Exposure Window test cases to new TRL encoding

keys with report type RECURSIVE are dropped by Android in Exposure
Window mode. The new encoding uses RECUSRIVE only with TRL 1 and 2
which are dropped anyway.

* 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.

* For cached (retrofit) response, we need to check the cacheResponse and its timestamps
to determine an accurate time offset.

* Exposure a boolean property to tell us when a fallback config is being used.

* Hide the observable flow<ConfigData> behind a method that can automatically triggers refreshes.

* Use a common mapper interface.

* set old risklevelcalculation deprecated

* Created skeleton for new risk calculation and aggregation

* Initial

* Implementing steps to aggregate results form exposure windows - wip

* Address PR comments and KLints.

* Fix refactoring regression.

* ktlint

* Json parsing

* Added ExposureWindowRiskLevelConfig and ExposureWindowRiskLevelConfigMapper for new config api (not yet introduced)

* Improve config unzipping code.

* Add flag to forward exception thrown during HotDataFlow.kt initialization.

* Don't specify a default context via singleton.

* Move download and fallback logic into it's own class just responsible for sourcing the config: "AppConfigSource".
"AppConfigProvider" is now only responsible for making it available.

* Check test cases

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

* Implementing steps to aggregate results form exposure windows

* cleaned todo

* Adjusted default values

* 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.

* refactored Windows aggregation

* 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

* removed example value

* Added missing import to WorkerBinderTest

* fixed unit tests

* Removed auto formatting on unrelated files (revert + cherry pick in other commit)
