Add addressType for network adapter, this allows to set a manual mac address in vSphere 5.5 (in addition to the mac field you added)

Add addressType to vSphere plugin, to allow to set the network adapter's addressType, for example to 'Manual'. This allows at least in vSpere 5.5 (but likely other versions too) to set a manual mac address in combination with the mac field you added in your clone.
