Allow server rebuild --wait for SHUTOFF servers

currently the command is waiting only for ACTIVE server status,
but if the server was SHUTOFF before, it will be SHUTOFF after
rebuild as well, so the command is stuck in waiting forever.

Additionally, we now also pre-validate the server status on client side,
and raise an error if the server to be rebuilt is not in ACTIVE, ERROR
or SHUTOFF state.
