New command to rollback firmware

From the FortiGate-6000 management board or the FortiGate-7000 primary FIM, you can use the following command to change the firmware image that the management board and all of the FPCs or all of the FIMs and FPMs load the next time the FortiGate-6000 or 7000 starts up.

execute set-next-reboot rollback

This command causes each component to select the firmware image stored on its non-active partition the next time the system starts up. This new command replaces the need to log into each component CLI and running the execute set-next-reboot {primary | secondary} command.
