[FLINK-18359] Log failures in handler instead of ElasticsearchSinkBase

This allows more control for the handler whether or not to log error
messages. In some cases, users know that they will get a lot of
failures, for example when back-filling existing data in ES. For those,
you don't want your log flooded with ERROR messages.
