    Do not prohibit VXLAN over IPv6
    
    9fc45cee in introduced a regression prohibiting using VXLAN over
    IPv6. Relax restriction on local_ip, but validate that both
    local_ip and vxlan_group of the same address family. Move existing
    validation of vxlan_group into validate_vxlan_group_with_local_ip()
    method and refactor existing tests for that validation.

Title:
  Neutron linuxbridge agent no longer accepts an IPv6 VXLAN local_ip

Status in neutron:
  Fix Released

Bug description:
  Neutron linuxbridge agent no longer accepts cfg.CONF.VXLAN.local_ip as
  an IPv6 address. Prior to 9fc45cee this restriction wasn't in place.
  Neutron ML2 with the linuxbridge mechanism driver had supported VXLAN
  over IPv6 since IceHouse.

  /etc/neutron/plugins/ml2/ml2_conf.ini:

  [DEFAULT]
  [ml2]
  tenant_network_types = vxlan
  extension_drivers = port_security
  type_drivers = local,flat,vlan,gre,vxlan
  mechanism_drivers = openvswitch,linuxbridge
  [ml2_type_flat]
  [ml2_type_geneve]
  [ml2_type_gre]
  tunnel_id_ranges = 1:1000
  [ml2_type_vlan]
  [ml2_type_vxlan]
  vni_ranges = 1001:2000
  [securitygroup]
  firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
  [agent]
  tunnel_types = vxlan
  root_helper_daemon = sudo /usr/local/bin/neutron-rootwrap-daemon /etc/neutron/rootwrap.conf
  root_helper = sudo /usr/local/bin/neutron-rootwrap /etc/neutron/rootwrap.conf
  [vxlan]
  local_ip = 2001:db8::10
  vxlan_group = ff05::10
  enable_vxlan = True

  When neutron-linuxbridge-agent is started, exits with:

  CRITICAL neutron [-] ConfigFileValueError: Value for option local_ip
  is not valid: 2001:db8::10 is not an IPv4 address
