CA-38971: Sometimes windows guests take a long time to shutdown cleanly. This patch lengthens the timeout time for clean shutdown requests from 20 minutes to 60 minutes.

Windows guests sometimes have genuine reasons to take longer than 20 minutes to shut down.

Possible reasons include:
* there are updates to install.
* the guest is overloaded.
* the host is overloaded.
