Cinder's my_ip is hard coded to HOST_IP instead of selecting based on SERVICE_IP_VERSION

[Ghanshyam Mann]

Devstack's lib/cinder set the my_ip on cinder side but it hard-code it with HOST_IP[1]. It is no issue for IPv4 env but when you build or run the IPv6 job then this ip is left to set with IPv6. my_ip should be set to HOST_IP or HOST_IPV6 based on SERVICE_IP_VERSION value.

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

    Set cinder's my_ip based on SERVICE_IP_VERSION value

    Devstack's lib/cinder set the my_ip on cinder side but it
    hard-code it with HOST_IP[1]. It is no issue for IPv4 env
    but when you build or run the IPv6 job then this ip is left
    to set with IPv6. my_ip should be set to HOST_IP or HOST_IPV6
    based on SERVICE_IP_VERSION value.

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