get_object_details to take query_filter and fallback to LDAP_USER_OBJECT_FILTER or LDAP_GROUP_OBJECT_FILTER

[jm66]

It'd be useful to provide queries to get_object_details at runtime. This provides flexibility when another query needs to be used temporarily without updating the global configuration. For example:

from app import ldap

user_dn_obj_filter = '(&(objectclass=inetOrgPerson)(entryDN=%s))'

ldap.get_object_details(user='cn=John Doe,ou=servauth-users,dc=users,dc=openldap,dc=org', query_filter=user_dn_obj_filter)
