Devstack to support an IPv6 infra installation

[Sridhar Gaddam]

Devstack to support an IPv6 infra installation where OpenStack services are binded to IPv6 addresses.

While testing such a setup, it is observed that some of the parameters are not configurable/set by devstack. Because of this, the respective openstack components would use the default values for some parameters (which generally fall-back to using the IPv4 address of the host)

    Set local_ip only when TENANT_TUNNELS are enabled

    In an installation with VLAN tenant networks, devstack should
    not configure the local_ip (which is applicable only when
    tenant_tunnels are used). This is causing failures in Neutron
    for an IPv6 only setup. This patch addresses this issue, but
    configuring the local_ip only when TENANT_TUNNELS are enabled.
