* Update protobuf format

* Addition of contentToFederation and visistedCountries/supportedCountries.

TODO: Unit tests, pull supportedCountries from AppConfig (waiting for #1213)

* Fix invalid package being assigned.
This would break daggers annotation processing as the class could not be resolved.

* Improved existing and implemented new tests.

* Fixed test regression due to refactoring.

* Integrate pulling the supportedCountries data from the AppConfig for the submission transaction.
(Previously wasn't implemented yet, now it's merged)

* Address merge conflicts, and a little refactoring, and a bit more tests.

* Revert file change to Project.xml

* AppConfigProvider should insert "DE" as fallback if the supportedCountry list is empty/not supplied.

* Don't insert the fallback country at application config provider level.
The UI requires the list to be empty, if it is empty in the config.
I've moved the fallback country insertion into the transaction.

* Make detekt happy.

* Make klint happy.

This reverts commit 6054bf57.

* Added first set of country flags

* Overhaul of DiagnosisKey related Download and Caching Mechanisms (EXPOSUREAPP-2469) (#1136)

* Rework of keyfile download and caching.
* Supports interop
* More modular for better testing and build flavour based behavior adjustments
* More resilient handling of failed downloads
* Preperations for future hourly download and serverside checksums

TODO: Finish unit tests, keycache migration and cache health check

* First batch of unit tests and some fixes for incorrect behavior that the tests surfaced.

* Added unit tests for the KeyCacheRepository

TODO: Tests for downloader and migration.

* Implemented POC for migration old key files.

* Fixed legacy file migration and cleanup, improved logging.

* Added unit tests for legacy key file migration.

* Add fallback for different file hashes in the header.

* Yes kLint, we know it's a long method,
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`

* 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.

* Added requestPadding property to all VerficationService requests

* Added fake calls to the WebReqeustBuilder

* 🚧

 initial draft to enable plausible deniability

* Switched from SubmissionConstants to KeyType enum everywhere

* basic playbook implementation with fake and real requests

* Playbook
- ensure request pattern for playbooks is always the same

VerificationService
- apply padding to ensure equal request size (header & body)

SecurityHelper
- extract hash256 to HashHelper. This simplifies tests that use only the hash function (and therefore don´t need to initialize SecurityHelper and its dependencies)

* Implemented random chance of dummy playbook execution on app open

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

* Playbook
- ignore exceptions for fake requests

SubmissionService
- add padding header to fake request for same header size

WebRequestBuilder
- include fake keys in upload (🏗️

)

* DiagnosisKeyService: removed (low value & difficult to test)

SubmissionService & SubmitDiagnosisKeysTransaction
- inline playbook & backgroundNoise property to prevent issues during testing

DiagnosisKeyConstantsTest, SubmissionServiceTest, SubmitDiagnosisKeysTransactionTest & SubmissionViewModelTest
- adjusted to changes

* Dummy playbook will now be repeated and delayed randomly

SubmissionService & VerificationService
- adjust header name for padding

WebRequestBuilder
- add padding to dummy submission

* BackgroundNoise is now trigger-only

PlaybookImpl
- include follow-up executions after every playbook
- logging

SubmissionViewModel.kt, SubmissionService.kt, SubmitDiagnosisKeysTransaction.kt, MainActivity.kt, BackgroundNoisePeriodicWorker.kt, DiagnosisTestResultRetrievalPeriodicWorker.kt
- propagate context for coroutine

VerificationService
- ensure body size of 1000

* WebRequestBuilder.kt

* - initialize coroutine scope within the playbook, revert passing it from outside
- remove experimental test dependency for coroutines

* - use single endpoint per server for fake requests
- reduce request size from 1000 to 250 for the verification server
- include dummy registration token in fake request to fulfill verification on server side
