MetricWithTimestamp function ignores the timestamp parameter while using the statsd client

[ajayvijendrang]

Expected Behavior

We would expect the metrics to show up with the timestamp that was passed in to MetricWithTimestamp function.

Actual Behavior

When the statdsclient is used to send metrics to Datadog, we see that the timestamp is being ignored and the current time is used instead. See here.

Steps to Reproduce the Problem

1. Send Distribution metric to datadog through the datadog lambda extension using the MetricWithTimestamp function.
