basecoin relay fixes

[ebuchman]

• should be able to handle basecli style key
• relay coin/amount should be configurable (or relay mechanics need to be changed to allow folks without coins to relay ... )

Easiest way to work with basecli style keys is to make it a basecli command.

Acutally, if you want users (non-full nodes) to run this, it makes sense in basecli.

[ethanfrey]

You want relay to work like basecli works, but as part of basecoin?

If it is meant to be run by people without full nodes, then I would suggest this. If it is meant to be run on full-nodes, then I am not sure why it should use basecli stuff?

We could have a randomly generated key.json and run full-node if you want. I am happy to make it a client command as well. I just don't like a mix of both, which usually assumes client and server on one machine, which is a dev situation, but not common in the real-world (I think).

[ebuchman]

My thinking was it should be in basecoin because its a long running process. But it needs access to a key, and we should have only one way we manage keys, ie. the basecli way ... Conflicted!

[ethanfrey]

basecli has a proxy command, which is long-running and emulates the tendermint rpc, only validating all responses.

[ethanfrey]

I need to improve the logging of these processes, but I actually think a local rpc server is the main use of basecli in the future, to provide security for a web ui.

[ethanfrey]

I could make a third command, for long running client processes?

basecoin, basecli, baseproxy?

Okay, after talking with bucky, we will:

1. Stick with 2 binaries for the time being (one for client, one for servers), although he is still not convinced we can't do it with one. I think server is a validating or non-validating node on an always-connected VM in the cloud. Client is my laptop/phone/etc. with my private key on my physical hardware. Commands go with the binary that fits the context.

2. There are lots of open questions if we allow multiple relays running in parallel. We should do a deeper refactor of this code before tackling that. As part of the bigger 0.7 release.

[ebuchman]

we'll revisit relay when we get IBC back on new sdk - but this should also be thought about in #324
