VideoPress: make video dashboard works with private media endpoint

[lhkowalski]

The VideoPress video dashboard uses the core /media endpoint to list and search videos, but it does an unauthenticated request to it.

Some users may want to turn the core /media endpoint private to prevent their videos from being listed by non-logged-in people. In this case, the VideoPress dashboard will not work properly.

We may need to investigate if it's possible to perform an authenticated request so even these users with private /media endpoints could use the VideoPress dashboard.

I found a strange behavior that seems buggy and might be related to video privacy configurations. I documented it on this issue, and I am commenting since I think the bugs could be associated. In summary, some videos marked as private on the Calypso media tab are still playable for logged-out users on an automatically created page on {yoursite}.com/{video-file-name}-mp4 but once you install the VideoPress plugin (not installed by default), the videos are not playable anymore on those pages (as they should be).
