onevm recover --recreate cannot be issued in POWEROFF state

[OpenNebulaSupport]

Description Remove the POWEROFF state limitation when issuing the one.vm.recover call with the --recreate flag. It currently excludes STOPPED, UNDEPLOYED, SUSPENDED and POWEROFF as states that the VM cannot be recovered from.

Use case For the case of the VM being POWEROFF, there is seemingly no reason to not be able to recreate the VM on that state.
