[FROG] pathspace for config files

[Casey Deccio]

Hi all,

I'm having trouble getting mgmtd to recognize my -N option for finding my config files:

$ sudo /usr/lib/frr/mgmtd -N r1 --log-level=debug --log=stdout

Seems like it should be looking in /etc/frr/r1/ for the config files, not /etc/frr//mgmtd.conf.

$ sudo /usr/lib/frr/mgmtd -h | grep pathsp
  -N, --pathspace    Insert prefix into config & socket paths

It works for the runtime files, which were created in the correct directory.

$ sudo ls -ltra /run/frr/r1/
