[Users] Network custom properties

Hello all, Introducing the oVirt 3.5 feature of network custom properties: http://www.ovirt.org/Features/Network_Custom_Properties Essentially, this feature aims to solve two RFEs, that request the ability to set bridge and ethtool options on host interfaces from the GUI/REST: https://bugzilla.redhat.com/show_bug.cgi?id=1080984 https://bugzilla.redhat.com/show_bug.cgi?id=1080987 It will do so by adding custom properties (key:value pairs) to networks assigned to host interfaces, which can in turn be acted upon via hooks when e.g. a Setup Networks command is triggered. Two predefined keys will include bridge_opts and ethtool_opts, but any arbitrary custom property could be supplied as well. Please take a look at the detailed feature page and let me know if you have any comments. Yours, Lior.
