Upgrade Path Enforcement for Managed FortiGates

In earlier versions of FortiManager, when upgrading FortiGate devices to a higher version than FortiManager, there was no check and the upgrade process would be completed. Managing higher version FortiOS devices with lower version of FortiManager caused issues.

This release includes multiple usability improvements to guide the administrator towards a successful upgrade.
