Code Issues Proposed changes

Add IPv6 support to devstack infrastructure 

By default, most Openstack services are bound to 0.0.0.0
and service endpoints are registered as IPv4 addresses.
With this change we introduce two new variables to control
this behavior:

SERVICE_IP_VERSION - can either be "4" or "6".

When set to "4" (default if not set) devstack will operate
as today - most services will open listen sockets on 0.0.0.0
and service endpoints will be registered using HOST_IP as the
address.

When set to "6" devstack services will open listen sockets on ::
and service endpoints will be registered using HOST_IPV6 as the
address.

There is no support for "4+6", more work is required for that.

HOST_IPV6 - if SERVICE_IP_VERSION=6 this must be an IPv6
address configured on the system.

Some existing services, like the Openvswitch agent, will continue
to use IPv4 addresses for things like tunnel endpoints.  This is
a current restriction in the code and can be updated at a later
time.  This change is just a first step to supporting IPv6-only
control and data planes in devstack.

This change is also partly based on two previous patches,
https://review.openstack.org/#/c/140519/ and
https://review.openstack.org/#/c/176898/

# IPv6
By default, most Openstack services are bound to 0.0.0.0
and service endpoints are registered as IPv4 addresses.
A new variable was created to control this behavior, and to
allow for operation over IPv6 instead of IPv4.
For this, add the following to `local.conf`:
SERVICE_IP_VERSION=6
When set to "6" devstack services will open listen sockets on ::
and service endpoints will be registered using HOST_IPV6 as the
address. The default value for this setting is `4`. Dual-mode
support, for example `4+6` is not currently supported.
