Setting up environment for media carousel view model

Since we only need to show the sorted list of media, there is no need to
use loading states. Instead, we can have them in a common model that
should be exposed by interactor. View-model should expose the list of
MediaCommonViewModel that contains view-models of either media controls
or recommendations and non-UI change actions. The common view-model will
be used by DiffUtil to figure out the events occured on the new list and
call actions.
