* origin/master:
  gitlab-ci: fix excluding @LargeTest from emulator jobs
  use TAG to identify CleanCacheWorker to WorkManager
  add WorkManagerTestRule to CleanCacheWorkerTest
  move static helper method into its class: CleanCacheWorker
  fdroidclient does not use variables for gradle dependencies
  Add WorkManagerTestRule.
  Use WorkManager to clean the cache.
  Add AndroidX WorkManager.
