David Subiros 0fb2ca8072 Vm state management and error states 
this implements the blueprint nova-vm-state-management
It implements the following functionalities:
- Filter compute api calls according to state of the VM
(defined in compute/state_checker).
- Sets error state if the scheduler cannot allocate the VM in any host
- Handles the create/delete concurrency in the compute manager
