First I backup a nova instance successfully, then I want to
restore it, I have created an action and a job, but the job
runned failed, I found an error in log of freezer agent:
"The parameter --nova-restore-network is required"
In the web form, the name of input field for network is called
"nova_network_id", but in the freezer project, it's called
"nova_restore_network".
