    Make placement client keep trying to connect

    In Newton, placement is optional and computes will stop even trying
    to connect to placement when they encounter an error or missing
    configuration. We really want them to keep trying so that enabling
    the service pre-upgrade does not require restarting all computes
    to start filling data.

    This patch removes the auto-disable logic and replaces it with a
    limited, but persistent warning to the logs about the required
    nature of placement for the upgrade. If we had messaged the upcoming
    requirement better, I think we could have been less chatty here.
    However, we know that it's not been received, so this patch periodically
    re-emits the warning and mentions the upgrade specifically.

    NOTE(mriedem): The conflict is due to 3c217acb9 not being in Newton.
