* If we revoked any cached keys we need to force an index lookup.
+ Additional tests to check that forced index lookup is decided on correctly.

* Fix merge regressions in tests.

The timeout checker doesn't need to force an app-config refresh, it's fine working with the latest available one. (#1573)

* 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.

* Add clear+download actions, and current network state display to the key download test fragment.

* Complete unit tests for KeyDownloadTool.kt

* 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.

* Fix last day/hour sync result success state not being updated.

* Change Key download task collision mode from ENQUEUE to SKIP_IF_SIBLING_RUNNING.

* Rename CalculationTracker to ExposureDetectionTracker

* 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.

* Dry sync/error logging call.

* Improve parameter naming, it's target locations, not available locations.
The app config alone determines which locations we try to sync.

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

* Fix test breaking on CI.

* 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

* 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.

* Address PR comments and KLints.

* Fix refactoring regression.

* 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.

* 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.
