E2e tests for chain upgrade

## Problem

We don't currently have e2e tests validating that a chain upgrade functions as expected. That is, no e2e test validates migration handlers. Gaia has a test for upgrade/migrations so we could pattern match that.

## Closing criteria

Make e2e for upgrade/migration of consumer and provider dummy apps

## Problem details

PRs like https://github.com/cosmos/interchain-security/pull/1037 that have migrations cannot be fully validated at this time. See https://github.com/cosmos/interchain-security/pull/1295
