[Tools] - fusiondirectory-configuration-manager --check-directories should check FusionDirectory and Orchestratrator permissions

Add an option to allow both arguments :

by default fusiondirectory-configuration-manager --check-directories should only check fusiondirectory without argument passed.

The path that need to be checked for FusionDirectory Orchestrator are :

mkdir /srv/orchestrator
mkdir /var/log/fusiondirectory

chown root:www-data /var/log/fusiondirectory/
chown root:www-data /srv/orchestrator/

Then:

chmod -R 770 /var/log/fusiondirectory/ 
chmod -R 770 /srv/orchestrator/
