DQ check is reading data from live data for both gracedb-playground and (live) gracedb

DQ checks on both gracedb-playground and gracedb are being performed from the same data, currently from /dev/shm/llhoft/{detector}/*.gwf (https://git.ligo.org/emfollow/gwcelery/blob/master/gwcelery/conf/init.py#L126-127). This means all the DQ flags and checks posted to gracedb-playground since the path was changed from {detector}_O2/*.gwf (replay) to {detector}/*.gwf (live) have been bogus.

To fix this, there needs to be different paths for different configurations of gwcelery. @leo-singer do you have any suggestions?
