[FSunstone] Examine allowed VM action states

[vichansson]

Description

Currently the VM terminate action is disabled for KVM VM's in the POWEROFF state. This should be enabled.

All VM actions should be restricted based on the state of the VM. These actions are driver-specific, and should be evaluated on a per-hypervisor basis. For reference, the following state diagram can be used: https://docs.opennebula.io/6.10/integration_and_development/references/vm_states.html#vm-states

The current implementation for actions and their respective allowed states can be found at: https://github.com/OpenNebula/one/blob/master/src/fireedge/src/client/constants/vm.js

To Reproduce

1. Instantiate any KVM VM
2. Trigger poweroff action
3. Attempt to terminate it normally

Expected behavior

Sunstone should allow you to terminate a KVM VM in the POWEROFF state
