Add support for sriovnicswitch and VXLAN offload
New configurations for fuel mellanox plugin to use sriovnicswitch mechanism driver for ethernet networks, it also gives the user the option to enable vxlan offloading to imporove performance and reduce CPU overhead. Change-Id: I480d4efb31fde126a51594bdbf48307a4e63ea74
