func QueryTendermintProof(
	clientCtx client.Context,
	key []byte,
) ([]byte, []byte, clienttypes.Height, error)

QueryTendermintProof performs an ABCI query with the given key and returns the value of the query, the proto encoded merkle proof, and the height of the Tendermint block containing the state root. The desired tendermint height to perform the query should be set in the client context. The query will be performed at one below this height (at the IAVL version) in order to obtain the correct merkle proof. Proof queries at height less than or equal to 2 are not supported. Queries with a client context height of 0 will perform a query at the lastest state available. Issue: https://github.com/cosmos/cosmos-sdk/issues/6567
