Implemented timestamps on builds

This feature allows the timestamps to be appended to the images built in order to properly select an image to consume based on the timestamp. This will allow previous images to be preserved in order to do regression testing if applicable.

+### Image Versions Based On Timestamps
+
+We have implemented the `{{ timestamp }}` function within Packer to append the
+timestamp to each image being built. This will allow for images to be continually
+built based on timestamp in order to properly select an image that you would like
+to consume.
+
+Example image built:
