Logging in qsfp_service about fboss

[bluecmd]

Digging around in folloy I found references to the --logging variable. That seems to have done the trick.

E.g.:

dhtech@wedge1:/usr/local/bin$ sudo /usr/local/bin/qsfp_service -alsologtostderr -v=2000 -vmodule='EventBase=0,AsyncSocket=0,CP2112=0' -mode=wedge  --logging=.=DBG3
