    Revert "Switch to use cast method in dhcp_ready_on_ports method"

    This reverts commit 1a686fb401eca1843b81292fc88c13a2e6fd274d.

    With https://review.opendev.org/#/c/709824/ and this reverted, we
    have seen things work better in our large scale environment. Although
    cast() will return immediately, it can overwhelm the server by sending
    a lot of messages quickly, and won't necessarily prioritize the "new"
    ones, which are typically more important to mark as provisioned first.
