    NetworkAgent: Handle VPN service aliases
    
    A VPN plugin can support multiple services, indicated by an 'aliases' key.
    
    We need to be able to spawn the appropriate auth-dialog for these aliases,
    as well as the base service.
    
    Covered as an afterthought (from comment 57) in
