Add a fake implementation of MediaStore content provider

[saket]

Is your feature request related to a problem? Please describe. Considering that robolectric already implements Environment.getExternalStoragePublicDirectory() and related functions for file storage, it'd be nice if context.contentResolver.insert("content://media…") and context.contentResolver.query("content://media…") functions were also usable in robolectric tests.

Describe the solution you'd like Could robolectric add a fake implementation of MediaStore?

There is something very very low quality here:

Also could Robolectric.setupContentProvider(ContentProviderClass, authority) help here?

You could create a fake MediaStore content provider.

Yep this is what I ended up doing, but it'd be really nice if I didn't have to maintain this code 😄. An implementation provided by robolectric would be battle tested.
