Remove usage of the deprecated IJobOptionSvc from legacy trigger configuration code:
DSConfigSvc:
IIOVDbSvc instead of reading
its property from the JobOptionsSvc.HLTConfigSvc:
IOptionsSvc, remove all code related to
reading prescales in a partition for the legacy trigger as we don't support this anymore.None of this should have an impact on the Run-3 trigger. There will be a separate MR for the TrigConf::JobOptionsSvc, which will need more thorough testing.
