(DIO-1522) Show the VM state (running, destroyed) and colorize in red when it has been deleted

the ABS system does not have a real sense of the current state of the resources
it has allocated. When running list --active it can list VMs that have been
deleted or reaped after their lifetime expired.
This change enables to show more information when a vmpooler_fallback service
is provided to ABS, and will show the state (running, destroyed) and colorize
in red when the VM is destroyed.
