This looks good to me. Any objections to merging as-is? Looks like keep-network/keep-core#1550 gave this a good exercising, so we should be good here.

We are not passing Value to CallMsg so the estimation may not be correct for payable functions. I think we need to generate a variation of estimate function just for payable functions.
It's not a top priority because the problem we are having in keep-network/keep-core#1479 is solved with the code here. I'll open a separate issue to address payable functions.

In this PR we add the gas estimation functionality. This will be used by Keep applications to retrieve the estimation for a specific transaction.
