abci++ / vote extensions

[Reecepbcups]

package by default within simapp, also an abci 'module' creator?

[Reecepbcups]

use https://github.com/cosmos/sdk-tutorials/tree/master/tutorials/oracle as a base

Would be nice to have a single file build everything (opt out of ABCI), then auto set it up.

Or like https://github.com/cosmos/interchain-security/blob/v5.0.0/app/consumer-democracy/abci.go

[Reecepbcups]

rewards-chain has a good base example once i build that further

[Reecepbcups]

relayer chain can be used as reference now. working impl over there since late June

I think this is useful, but not a priority till it’s requested. much higher priority items to focus on currently.
