Beta & RC Testing Ops

[clevinson]

Some pieces we should add for smoother testing of SDK upgrades:

• A) devnets running in CI that can be used for functional testing. Add devnets in CI #9183
• B) scripts for taking a live chain and performing upgrade migration testing with minute-long voting period. Story Points: 34

B) migration test script

The migration test script basically needs to:

• take an exported genesis from a live chain
• change the chain-id
• change the validator set and staking power to run with 1+ test nodes
• change the voting period to a short time (minutes rather than weeks)
• spin up a local network on a single machine with each node running the old binary + cosmovisor provisioned with the new binary
• run an upgrade proposal
• run some functional tests after the nodes upgrade with cosmovisor. This may need to be done manually...

This script probably can't be run in CI because of the need to have an exported genesis from a full node and two different binaries. So we need manual testing for this.

@clevinson I think we can spin up make localnet-start in a GH actions environment
