This PR adds code to appropriately handle versioning issues that come up quite constantly across our API changes. Currently we were also routing our requests wrong which sort of made it harder to write a consistent error handling code to appropriately reject or honor requests. This PR potentially fixes issues - old mc is used against new minio release which is incompatible returns an appropriate for client action. - any older servers talking to each other, report appropriate error - incompatible peer servers should report error and reject the calls with appropriate error
