Adds SpotQueuedAtMs attribute which will store a Millisecond unix timestamp which represents when a SPOT request has been queued. We will use this at SPOT response handler to caclulate the response time of SPOT I have made this a boxed Long,as there are some cases in which SPOT will not be queued (such as in the return code scenario)
We would like to time how long SPOT takes per journey, and to do this we need to persist the timestamp, in milliseconds, of when we queued a SPOT request. We can't do this in metrics becasue it would generate a unique metric with new dimensions per journey. Instead we can store the timestamp on serialising the identity credentials in dynamo. Then we can compare this on SPOT response to get a measure of how long SPOT takes
Now we're storing the queued at timestamp, we can now emit a metric for the latency of SPOT, calculating the difference between now and the time at which the request was queued
