Setup framework for IPv6-only deployment verification

Devstack IPv6 base job 'devstack-IPv6' setup the IPv6 setting
to deploy the services to listen on IPv6 address.

Tempest 'devstack-tempest-ipv6' job derived from 'devstack-IPv6'
job adds the playbooks to run the tests.

As part of Train community goal 'Support IPv6-Only Deployments',
we will expand the 'devstack-tempest-ipv6' job to do
IPv6-only deployments verification.

This commit define the new roles of 'ipv6-only-deployments-verification'
which will be invoked as part of run phase of 'devstack-tempest-ipv6' job.
This role will do IPv6-only setting and deployments verification via
tools/verify-ipv6-only-deployement.sh

IPv6 verification script can be extended further to perform more checks
and via project specific test case. Those tests will run as part of project
specific child jobs.

The 'devstack-tempest-ipv6' job will be used as parent for project specific
IPv6-only job. Those child job can extend the project specific IPv6 verification
by defining new playebook for post-run. That way the base verification
done in 'devstack-tempest-ipv6' will still run in addition to project specific
verificaiton and tests run.

Verification structure will be:
- 'devstack-IPv6' deploy the service on IPv6
- 'devstack-tempest-ipv6' run will verify the IPv6-only setting and listen address
- Child jobs derived from 'devstack-tempest-ipv6' will run the IPv6 related test case or
  any further IPv6 deployment verification.

This commit also adds the new job 'tempest-ipv6-only' which will run smoke
and ipv6 related tests present in Tempest. This job will be used to run
on 6 services (Nova, Neutron, Cinder, Keystone, Glance, Swift) deployed
by devstack.
