test: load the video from storj instead of cloudflare

[tushar-saxena-yral]

Switches the video retrieval from cloudflare to trial account's storj bucket. All the videos that are seeded by backend are loaded into my storj bucket.

For now, to try it out:

• switch to test/storj-backed-feed
• keep backend image locally
• ./local-run.sh

I can barely feel the difference, but I welcome everyone to give it a shot at least once.

I also ran some simple bench marks to get some numbers:

Average download speed reported by curl for downloading 102 files with a size
range of ~[500kb, 10mb]


Storj ====================================
	Mean: 2.07316e+06 bytes/s
	Median: 1695713.5 bytes/s
	Standard Deviation: 1426472.75 bytes/s

Cloudflare ===============================
	Mean: 4.72868e+06 bytes/s
	Median: 3750166 bytes/s
	Standard Deviation: 3376576.21 bytes/s

Cloudflare is 2x faster than storj

But it barely makes a difference in practice.
