This change adds more richer error response
for JSON-RPC by interpreting object layer
errors to corresponding meaningful errors
for the web browser.
```go
&json2.Error{
Message: "Bucket Name Invalid, Only lowercase letters, full stops, and numbers are allowed.",
}
```
Additionally this patch also allows PresignedGetObject()
to take expiry parameter to have variable expiry.
