rolling_update: move osd flag section

During a minor update from a jewel to a higher jewel version (10.2.9 to
10.2.10 for example) osd flags don't get applied because they were done
in the mgr section which is skipped in jewel since this daemons does not
exist.
Moving the set flag section after all the mons have been updated solves
that problem.
