:scroll: Description

• Timeouts in SqsTemplate were being set by calling Duration#getSecondsPart which is always a number between 0 and 59
• Update to use Duration#getSeconds to get the full timeout specified, in seconds

:bulb: Motivation and Context

This supports using a visibility time and polling timeout that's greater than 60 seconds.
