remove log-min-dur

introduced via 929513c / #174
became obsolete in b3d3831 / #575 / 0.7.1-61-gbe64803e

we no longer really log requests ourselves anymore.
i imagine at some point we probably will, at which point we can
re-introduce this setting

(our qa tool `unused` notified that this variable wasn't being read
anywhere)
