[Users] vnic : add a custom properties and use it in vdsm_hook

Hello Evrybody, Is there a way to add custom properties for a nic ? and use it in vdsm_hooks ? The objectife is to redefine some network parameters of a vnic at the vm boot ... (such per vnic bandwitchs, per vnic vlan, and so on) and maybe use openvswitch ... Thank you in advance -- -- Benoit
