By default, the temporary security credentials created by AssumeRoleWithWebIdentity last for one hour. However, the optional DurationSeconds parameter can be used to specify the validity duration of the generated credentials. This value varies from 900 seconds (15 minutes) up to the maximum session duration of 365 days.

 * <p>Durations are represented by an integer, followed by one of "d", "h", "m", or "s",
 * representing days, hours, minutes, or seconds respectively. (There is currently no syntax to
