AthenaMonitoring: Move code from begin/endRun to start/stop
begin/endRun are deprecated. For jobs that only process one run at a time, executing the code in start/stop is equivalent.
@ponyisi I think this should be safe. This of course only affects the legacy (serial) DQ monitoring. This is one of the last clients that makes use of those methods before we can entirely remove them from Gaudi.
