Configuration files migrated from lemonldap-ng-fastcgi-server to lemonldap-ng-handler

Testing upgrade from v1.9 to v2.0 using packages from https://lemonldap-ng.org/deb, we encountered an issue due to /etc/lemonldap-ng/nginx* getting installed in lemonldap-ng-handler instead of lemonldap-ng-fastcgi-server.

Manually overriden using apt-get -o Dpkg::Options::="--force-overwrite" install lemonldap-ng-handler but still problematic in case of automated upgrade.
