Android emulator.Add script and manual CI jobs (#853)

Script do:
 - build SDK with needed options for Android
   (API=25,ABI=arm64-v8a)
 - create AndroidVirtualDevice(AVD)
 - start AVD via embeded SDK emulator
 - run trivial adb command to check that device is ON.
   (.apk installation to be added later)
Everything can run on:
 - Gitlab CI by using our Android image
 - Azure Pipelines CI by using MacOS image.
