Add upgrade notification for system commands

During upgrade, system commands:
host-pv-list, host-pv-show, host-lvg-list, host-lvg-show,
host-disk-partition-list, and host-disk-partition-show could display
the host configuration that will be applied to host after upgrade. A
notification message is displayed in the above commands to inform
the user.

Test Plan:
    Run commands during an upgrade, verify proper message is displayed.
    Run commands when upgrade is not in progress, the notification
message is not displayed.
