Allow multiple videos for redundancy instances

[vid-bin]

Describe the problem to be solved

Currently redundancy instances appear to be limited to one video at a time.

The default nginx configuration limits this to 50Mbps with the rate limit options. So for a redundancy instance that has 2TB+ storage it will take a long time to fill.

Describe the solution you would like

Either allow trusted redundancy instances to do more then one video at a time or modify the nginx configuration to have a whitelist option for redundancy servers.

Because the current setup allows any "followers" to do redundancy it would be best to make the whitelist option an actual checkmark or something so you can only include your own servers in the whitelist.
