          erp5_cluster: leave ERP5 set the haproxy cookie
    the balancer will overwrite this cookie's value, so do not compare it
    to our name: balancer may be calling us a name completely unrelated to
    the value getCurrentNode returns.
    So simplify this function's logic to only do what the docstring says:
    decide when to set and when to unset the balancer cookie, and let the
    balancer decide the value.
    This resolves cases where Zope would set the cookie over and over on
    every request when getCurrentNode and balancer disagree on its value.
