vm in shutdown status doesn't occupy Ram or Vcpu resouce
As we know,When the VM is in shutdown status , nova host resource manager still consider it occupy the host's resources. In some situations, Host's resource should be controled by users .
In that case,there is a serious problem that if boot a vm in shundown status and the host doesn't have enough resource,the vm will in error status. So, a migrate operator is needed here.
Goals:
1. Add a shutdown resouce release feature to nova-compute.
2. Add a migrate operate before start a vm , when host's resouce is not enough .
