the class ConfigurationAsmGenerator method addConfigurationImplConstructor.

/**
 * Implements default constructor for the configuration class. It initializes all fields and adds them to members collection.

 * @param fieldDefs Field definitions for all fields of configuration impl class.
 * @param schemaFields Fields of the schema class.
 * @param internalFields Fields of internal extensions of the configuration schema.
 * @param polymorphicFields Fields of polymorphic extensions of the configuration schema.
 * @param internalIdField Internal id field or {@code null} if it's not present.
 * @param internalConfigTypesFieldDef Field definition for {@link DynamicConfiguration#internalConfigTypes},
 *      {@code null} if there are no internal extensions.
