IBC testing

[iboss-ptk]

To be able to test cross-chain CosmWasm contract, test-tube needs to be able to relay IBC packet across.

As suggested by @ethanfrey & @alpe, since the idea of test-tube is similar to how ibctesting is constructed, which we can take inspiration from for enabling IBC testing for test-tube.

I think using interchaintest could be a nicer way to execute this.

Basically do away with the current chain spawn. Spin up an environment using Interchaintest specification for multiple chain processes and later use RPC to send Execute/ Query messages to each respective chain instead of running within the same process.

Do you see any potential issues with it?

I think what I want for test tube is to avoid is upfront orchestration cost in order to run integration test (between contract, chain and other chains, not of a real env). With that, it run faster easier to control the environment.

But if I'm not understanding you correctly. please lmk.

Hello have you made any progress in that direction ?
cw-orch could really benefit from this feature !
