    circleci: Bump down thread count
    
    It appears that our jobs generally run on VMs with 2 vCPUs. Consequently running
    with 8 jobs will completely oversubscribe the machine. I suspect this is the
    cause of #14453. Let's bump this down to 3 for now. Ideally we would determine
    this from the environment.
