Yeah this is a smoke test for the (already committed) leader election onchain config change planned for next release.

What I think we need to be able to do, to have smoke tests for governance proposals like these (which we really should have - otherwise they are not continuously tested):

• be able to set genesis onchain config. This basically tests a revert, because genesis is now new. I'll try to add this to smoke tests
• wrappers for generating proposals like these, and executing governance - i.e. we shouldn't need every smoke test to implement that
• be able to set smoke-tests to run nightly. this tests for example runs for multiple minutes, so not great to have it run on every PR :/

I'll include the consensus config in the proposal generator!

Argh, I had these PRs stacked, merging this one doesn't merge in main @runtian-zhou .

since this PR is marked as merged, I needed to recreate it - #5594
