Add configurable parameters for statsd client (#16283)
Statsd client sometimes drops metrics when this queueSize of statsd client with max unprocessed messages is completely full. This causes some high cardinality metrics like per partition lag being droppped.
There are multiple parameters of statsdclient that can be initialized and can help increase the load/capacity of client to not to drop metrics more frequently.
Properties like queueSize, poolSize, processorWorkers and senderWorkers will now be configurable at runtime

Extension to read and ingest iceberg data files (#14329)
This adds a new contrib extension: druid-iceberg-extensions which can be used to ingest data stored in Apache Iceberg format. It adds a new input source of type iceberg that connects to a catalog and retrieves the data files associated with an iceberg table and provides these data file paths to either an S3 or HDFS input source depending on the warehouse location.

Two important dependencies associated with Apache Iceberg tables are:

Catalog : This extension supports reading from either a Hive Metastore catalog or a Local file-based catalog. Support for AWS Glue is not available yet.
Warehouse : This extension supports reading data files from either HDFS or S3. Adapters for other cloud object locations should be easy to add by extending the AbstractInputSourceAdapter.

Adding SegmentMetadataEvent and publishing them via KafkaEmitter (#14281)
In this PR, we are enhancing KafkaEmitter, to emit metadata about published segments (SegmentMetadataEvent) into a Kafka topic. This segment metadata information that gets published into Kafka, can be used by any other downstream services to query Druid intelligently based on the segments published. The segment metadata gets published into kafka topic in json string format similar to other events.

Various documentation updates. (#13107)
* Various documentation updates.

1) Split out "data management" from "ingestion". Break it into thematic pages.

2) Move "SQL-based ingestion" into the Ingestion category. Adjust content so
   all conceptual content is in concepts.md and all syntax content is in reference.md.
   Shorten the known issues page to the most interesting ones.

3) Add SQL-based ingestion to the ingestion method comparison page. Remove the
   index task, since index_parallel is just as good when maxNumConcurrentSubTasks: 1.

4) Rename various mentions of "Druid console" to "web console".

5) Add additional information to ingestion/partitioning.md.

6) Remove a mention of Tranquility.

7) Remove a note about upgrading to Druid 0.10.1.

8) Remove no-longer-relevant task types from ingestion/tasks.md.

9) Move ingestion/native-batch-firehose.md to the hidden section. It was previously deprecated.

10) Move ingestion/native-batch-simple-task.md to the hidden section. It is still linked in some
    places, but it isn't very useful compared to index_parallel, so it shouldn't take up space
    in the sidebar.

11) Make all br tags self-closing.

12) Certain other cosmetic changes.

13) Update to node-sass 7.

compressed big decimal - module (#10705)
Compressed Big Decimal is an extension which provides support for 
Mutable big decimal value that can be used to accumulate values 
without losing precision or reallocating memory. This type helps in 
absolute precision arithmetic on large numbers in applications, 
where greater level of accuracy is required, such as financial 
applications, currency based transactions. This helps avoid rounding 
issues where in potentially large amount of money can be lost.

Accumulation requires that the two numbers have the same scale, 
but does not require that they are of the same size. If the value 
being accumulated has a larger underlying array than this value 
(the result), then the higher order bits are dropped, similar to what 
happens when adding a long to an int and storing the result in an 
int. A compressed big decimal that holds its data with an embedded 
array.

Compressed big decimal is an absolute number based complex type 
based on big decimal in Java. This supports all the functionalities 
supported by Java Big Decimal. Java Big Decimal is not mutable in 
order to avoid big garbage collection issues. Compressed big decimal 
is needed to mutate the value in the accumulator.
