    Periodic message loss between VIM and Openstack pods

    The requests to Openstack services hang/fail sometimes
    due to message loss when connecting to internal service
    endpoints. This issue was observed before and fixed in
    commit https://review.opendev.org/#/c/683818/ by setting
    net.ipv4.tcp_tw_reuse to 0, however, it's still being
    seen on recent STX loads.

    It has been tested and proved that requests go through
    ingress pod do not have the issue.

    Update the default keystone auth endpoint to public url
    in sysinv so VIM and pci-irq-affinity-agent can be
    configured to talk to keystone using public urls.
    Aslo update the requests from VIM to nova to go through
    ingress as well.
