Whitelist and Blacklist Fields When Encoding

We've added the ability to white-list and blacklist fields during the encoding process within sinks. This is useful if you have metadata fields that you do not want to send downstream. For example, you might have an application_id fields that you use for partitioning, but you don't want to include it in the actual data since it would be duplicative.

To use this feature see the new encoding options for each sink. For example, the clickhouse sink's encoding option.
