(NetBox) Allow custom LDAP attributes

[k-304]

Allow NetBox to populate user profiles with custom LDAP attributes defined in Ansible.

The default in NetBox is:

netbox__ldap_attr_firstname: 'cn'
netbox__ldap_attr_sn: 'sn'
netbox__ldap_attr_mail: 'mailAddress'

But our LDAP has a cn including givenName + surname, and we get duplicated entries in the name field in NetBox. We'd want to use custom LDAP attributes instead.

No longer needed. Could not replicate issue.
