Introduce power in the opted-in state so we can see if we should send a ValidatorUpdate down to CometBFT based on whether the power changed since last time it was sent. Only makes sense in an epoch-based setting because in a non-epoch-based setting, we could use the validator updates from the staking module.

) {
store := ctx.KVStore(k.storeKey)

// validator is considered opted in
blockHeightBytes := make([]byte, 8)
binary.BigEndian.PutUint64(blockHeightBytes, blockHeight)

store.Set(types.OptedInKey(chainID, providerAddr), blockHeightBytes)
powerBytes := make([]byte, 8)
binary.BigEndian.PutUint64(powerBytes, power)

store.Set(types.OptedInKey(chainID, providerAddr), append(blockHeightBytes, powerBytes...))

Store OptedInValidator as a value (define it in the proto files).

Is the recommendation here to define it in proto to simplify our life later on when we implement queries that return opted-in validators?
