xud Translate gRPC calls to make them CCXT-compatible

We aim to make xud's main calls ccxt compatible, so that professional traders can easily connect their existing GUI + algorithms. As per https://github.com/ExchangeUnion/xud/issues/471#issuecomment-441451581 we will not start a GUI project on our own.

Here is the full list of all unified ccxt API methods (subset of methods common among the exchanges) which we should support. I suggest to do this with a ccxt wrapper, not touching existing calls. The CLI is not affected and can stay as is. Goes without saying - we'll keep all other calls as is

@kilrau Is anyone planning to work on this? if not I will take it.

Please, but let's discuss on the way how to do this - if via ccxt wrapper around our current gRPC or change the gRPC

@kilrau @sangaman We should discus this on the weekly meeting.

I'm not familiar with CCXT and I don't think it's been brought up on one of the calls, but we can discuss next time. I'd expect that it'd be better to have a wrapper around our existing API.

That's what I thought too!

Please bring this up on our next call on Wednesday and definitely don't accept that we skip you again! ;)

CLI is enough for 1.0.0. Moving to post-1.0.0.

Is this open to work? I would like to take this if this is avaible to work. And if I can work on this, can you give estimation salary?

It is! Added estimation. I suggest to keep us in the loop on how exactly you plan to implement this to make sure you are heading into the right direction!

@kilrau I think we need provide http api on xud if we want to use api trough ccxt. So I'll create grpc services for every ccxt api endpoint?

gRPC is HTTP(/2)

gRPC wrapper services, internally pointing to the existing gRPC calls. That's at least how I imagined it. Thoughts? @sangaman @erkarl

I would like to take care of https://github.com/ExchangeUnion/market-maker-tools/issues/1 first though.
