Add optional debug level to slapd

[ultrotter]

Hi!

Testing your image, in case of errors it's very hard to know what's wrong. Would you consider calling slapd with something like:

exec /usr/sbin/slapd -u $USER -g $GROUP -d ${SLAPD_DEBUG:-0} -h "ldap:/// ldaps:///" -f /etc/ldap/slapd.conf
So that one can increase the verbosity level, please?

Thanks,

Guido

sure, have a look at 1492230 and test the :main tag

let me know if that solves your issue
