support stream through IPFS daemon

[pgte]

One of the reasons why we were not able to use an IPFS daemon instead of an embedded js-ipfs node was because go-ipfs didn't allow for p2p streams. But go-ipfs now it does have the p2p command which opens a duplex stream.

for clarity, this would work through companion, correct?

[pgte]

Apparently js-ipfs does not support this, so I think companion doesn't either. Opened respective issue on js-ipfs for clarification.

So go-ipfs exposes libp2p streams via ipfs p2p for quite a while already, but it's not really useful for browsers since it requires use of native sockets.

There was some discussion on creating a websocket interface to these commands to enable browsers to open/listen for p2p streams, but iirc the conclusion was to focus on https://github.com/libp2p/go-libp2p-daemon, and just support websockets there

(AFAIK it should be possible to implement on the extension level, cc @lidel)

@magik6k ha, thanks for the feedback! If it's not websockets we can't use it directly in the browser context, and we would need this to be in the IPFS daemon..
