Upstream integration testing functionality from cosmos-sdk-rs?

[tony-iqlusion]

#942 (which I'm basically responsible for) seems like the sort of problem which would've been caught easily by a live integration test against a Tendermint RPC endpoint.

I wrote a handful of simple utility functions to assist integration testing against a single-node gaiad as part of cosmos-sdk-rs:

https://github.com/cosmos/cosmos-rust/blob/7ff213318ddc93440bbe6030e8258631b2bd8b59/cosmos-sdk-rs/src/dev.rs

Would there be any interest in upstreaming these to tendermint-rs? It seems useful for e.g. integration testing tendermint-rpc in a way which could run as part of CI.

We currently have integration testing against the kvstore in the tools folder, as well as our rpc-probe which we usually use to generate fixtures for the RPC tests (see here).

We just need to generate those fixtures for the /tx endpoint and add an integration test against the kvstore and we'll automatically detect regressions here in CI.

Aha, sounds good then
