Subject: [PATCH] maintainers/haskell/hydra-report.hs: allow disabling log
 requesting

Since every failure in the jobset means one request to get the log when
generating the list of newly broken packages, we need to add an option
to disable log requesting in case a lot of new breakage needs to be
entered.
