ml2_conf.ini miss a section for VXLAN

[Emilien Macchi]

1) First issue: [ml2_type_vxlan] section is missing in ml2_conf.ini configuration file.
cfg.CONF.register_opts(vxlan_opts, "ml2_type_vxlan")

2) Second issue: vxlan_group flag should not be in [ml2] section, but in [ml2_type_vxlan] which is not present (first issue).

3) Third issue: vni_ranges flag is missing, and need to be in [ml2_type_vxlan] section.
