Kajona\Workflows\System\WorkflowsHandlerInterface::getConfigValueNames

Each handler can be condigured using a set ot three values. It is up to the implementation if the fields are used to store a list of values, e.g. separated by |.

The third field is of type text and therefore can consume up to about 65k chars. The first and the second field are varchars limited to 254 characters. The method should return an array of three string, indicating the names of the values - if required. Otherwise returning an empty array will result in the usage of the default names.
