By running these database queries within the file serving code, this PR significantly slows the loading of all preview media so we might want to do this out of band.

Without this check disabled the node will just fallback to the placeholder instead of making a request over P2P to the other node for the file.
Obviously disabling it like i've done here is not a permanent solution.

With the current implementation this can be called as:
platform.getThumbnailUrlByThumbKey("ephemeral", itemData.casId)platform.getThumbnailUrlByThumbKey(library.uuid, itemData.casId)
As the codebase has no calls using the "ephemeral" variant I am certain this PR breaks thumbnails for the ephemeral explorer.

lets get this picked up @ameer2468 |
This PR builds on top of #2523 to allow thumbnails to be served via P2P from the node where the file exists.
Although we will sync preview media, having the ability to serve it over P2P means we can suffice before the first sync and we can also support scenarios were only a portion of the preview media is sunk.
