> Instead of requiring 3 separate inputs from the user for upgrading (for uninstall, reconfigure, and deploy), just have the user click on the "Upgrade Now" button after specifying the SSH private key file.  Ask the user for confirmation (as it will first uninstall the stack as part of the upgrade process).  Once the user confirms, the SSH private key file is uploaded and the upgrade process is triggered; there's no further input required from the user until the upgrade completes successfully, or if there's an issue that requires the user to fix (after fixing the problem, the user can click on "Retry" to continue with the upgrade process).
