ci: Implement ibc-test-framework-based integration test for basecoin-rs

[thanethomson]

We want to eventually upgrade the current integration tests in CI to make use of ibc-test-framework for integration testing as opposed to our current BASH script-based approach.

Acceptance Criteria

When we have an integration test in CI that makes use of ibc-test-framework instead of the current BASH script-based approach. This must test at least one kind of meaningful set of functionality, like ft-transfer, between a gaiad chain and a basecoin-rs chain.
