Appends handy timer information to curl's stderr, giving the user a simple way to understand the duration of a requestion.
Takes a scalar of seconds and renders them as a string. If you are subclassing this plugin to add color coding, for example, you just need to override this method.
(internal) wraps the curl command to get timing data and append the duration.
