    Make auto-allocate plugin handle sneaky DB errors

    DB errors or retry exceptions that bubble up to the
    plugin may get masked by integrity violation errors
    due to partial provisioning of resources. When that
    happens, we should make sure any pending resource
    is cleaned up before reattempting the operation.
