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.

Update Hadoop3 as default build version (#14005)
Hadoop 2 often causes red security scans on Druid distribution because of the dependencies it brings. We want to move away from Hadoop 2 and provide Hadoop 3 distribution available. Switch druid to building with Hadoop 3 by default. Druid will still be compatible with Hadoop 2 and users can build hadoop-2 compatible distribution using hadoop2 profile.

Add JWT authenticator support for validating ID Tokens (#13242)
Expands the OIDC based auth in Druid by adding a JWT Authenticator that validates ID Tokens associated with a request. The existing pac4j authenticator works for authenticating web users while accessing the console, whereas this authenticator is for validating Druid API requests made by Direct clients. Services already supporting OIDC can attach their ID tokens to the Druid requests
under the Authorization request header.

Improve memory efficiency of WrappedRoaringBitmap. (#13889)
* Improve memory efficiency of WrappedRoaringBitmap.

Two changes:

1) Use an int[] for sizes 4 or below.
2) Remove the boolean compressRunOnSerialization. Doesn't save much
   space, but it does save a little, and it isn't adding a ton of value
   to have it be configurable. It was originally configurable in case
   anything broke when enabling it, but it's been a while and nothing
   has broken.

* Slight adjustment.

* Adjust for inspection.

* Updates.

* Update snaps.

* Update test.

* Adjust test.

Removes FiniteFirehoseFactory and its implementations (#12852)
The FiniteFirehoseFactory and InputRowParser classes were deprecated in 0.17.0 (#8823) in favor of InputSource & InputFormat. This PR removes the FiniteFirehoseFactory and all its implementations along with classes solely used by them like Fetcher (Used by PrefetchableTextFilesFirehoseFactory). Refactors classes including tests using FiniteFirehoseFactory to use InputSource instead.
Removing InputRowParser may not be as trivial as many classes that aren't deprecated depends on it (with no alternatives), like EventReceiverFirehoseFactory. Hence FirehoseFactory, EventReceiverFirehoseFactory, and Firehose are marked deprecated.

Kinesis: More robust default fetch settings. (#13539)
* Kinesis: More robust default fetch settings.

1) Default recordsPerFetch and recordBufferSize based on available memory
   rather than using hardcoded numbers. For this, we need an estimate
   of record size. Use 10 KB for regular records and 1 MB for aggregated
   records. With 1 GB heaps, 2 processors per task, and nonaggregated
   records, recordBufferSize comes out to the same as the old
   default (10000), and recordsPerFetch comes out slightly lower (1250
   instead of 4000).

2) Default maxRecordsPerPoll based on whether records are aggregated
   or not (100 if not aggregated, 1 if aggregated). Prior default was 100.

3) Default fetchThreads based on processors divided by task count on
   Indexers, rather than overall processor count.

4) Additionally clean up the serialized JSON a bit by adding various
   JsonInclude annotations.

* Updates for tests.

* Additional important verify.

Async task client for SeekableStreamSupervisors. (#13354)
Main changes:
1) Convert SeekableStreamIndexTaskClient to an interface, move old code
   to SeekableStreamIndexTaskClientSyncImpl, and add new implementation
   SeekableStreamIndexTaskClientAsyncImpl that uses ServiceClient.
2) Add "chatAsync" parameter to seekable stream supervisors that causes
   the supervisor to use an async task client.
3) In SeekableStreamSupervisor.discoverTasks, adjust logic to avoid making
   blocking RPC calls in workerExec threads.
4) In SeekableStreamSupervisor generally, switch from Futures.successfulAsList
   to FutureUtils.coalesce, so we can better capture the errors that occurred
   with contacting individual tasks.

Other, related changes:
1) Add ServiceRetryPolicy.retryNotAvailable, which controls whether
   ServiceClient retries unavailable services. Useful since we do not
   want to retry calls unavailable tasks within the service client. (The
   supervisor does its own higher-level retries.)
2) Add FutureUtils.transformAsync, a more lambda friendly version of
   Futures.transform(f, AsyncFunction).
3) Add FutureUtils.coalesce. Similar to Futures.successfulAsList, but
   returns Either instead of using null on error.
4) Add JacksonUtils.readValue overloads for JavaType and TypeReference.

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.
