Add Iceberg support

[nextdude-mdsol]

• Add support for iceberg table format (both as a source and sink).
• Added support for kinesis firehose sink.
• Swap kinesis sink to AWS v2 SDK version in flink-connector-aws-kinesis-streams
• Standardize kinesis sink configuration across firehose and streams sink connectors
• Refactor SourceConfig and SinkConfig to inherit from a common SourceOrSinkConfig trait to enable common configuration processing across source and sink configs.
• Refactor SinkConfig.get*Sink() methods to return Unit instead of DataStream[E] and rename them to add*Sink(). This simplifies their usage since their return value was never used and not all sinks return DataStreams (like Cassandra and Iceberg) as easily as some other Flink sink apis.
• Add EmbeddedRowType trait to support converting FlinkEvent instances to Row objects for use with Row type sinks, like Iceberg
• Created a TableStreamJob job class to support jobs that sink to Row type sinks, like Iceberg.
• Upgrade to flink 1.16.1
