add "show providers" option to explore page

[whyrusleeping]

It would be really cool if when i load an object in the dag viewer, i could click a button to retrieve a list of providers of the object i'm looking at.

from the CLI, this is done with ipfs dht findprovs <hash>

I have the basics in place to make this happen now, will postpone until after next release.

@krl if you were having trouble with the output of findprovs, try this patch: http://mars.i.ipfs.io:8080/ipfs/QmbTY1cgy33noZU9skA5PHAJeL4fsbLTPwBRfVU3Twz539

and make sure to add stream-channels=true to your query, like:
curl localhost:5001/api/v0/dht/findprovs/QmbbowxNyjgNcY9qwJPr4JAGP7A9vdkipoihF5jAkgahiY\?stream-channels=true

[krl]

@whyrusleeping will try it as i set up multi-node api tests, is this part of a pull request somewhere?

(note: transferring this into the ipld-explorer repo, makes more sense there.)

@whyrusleeping - this is a very old issue but wondering if it might be worth opening up to bounty. Thoughts?
