Setup a latest-SDK test environment to run queries against

[ebuchman]

While the SDK is in flux and the Go relayer is not updated, it's hard to set up a test environment to run queries event.

We need to get a set of data we can query against so we can actually run and test queries.

One option is to try to figure out how to setup an SDK chain prepopulated with a bunch of IBC state so we can query it. Another option is to try and get the relevant JSON out and use those as fixtures to run "queries" against. Either option will require some digging into the SDK to figure out how to set up IBC state.

SDK has a built in simapp which is basically the same functionality as gaia. Not sure if we can run it as a process and query against it but we need to investigate.
