Add support for writing tags along with events to Sink.

Some events may be tagged in the DataPrepper. Need a way to write these tags to Sink along with the event data.

Describe the solution you'd like
Provide a sink level config option to write tags along with events. When this option is used, the tags in the events should be written to the sink under the key provided with the config option. For example.

opensearch:
    ...
    tags_key_name: "tags"

The implementation should support all sinks without having to write sink specific configuation support.
