Go client cannot form Put message properly

[buraksezer]

The Go client uses wrong type of extra to form a protocol message for protocol.OpPut

req.SetExtra(protocol.PutExExtra{
  Timestamp: time.Now().UnixNano(),
})

This leads an empty Timestamp field. It should be like this:

req.SetExtra(protocol.PutExtra{
	Timestamp: time.Now().UnixNano(),
})
