This PR upgrades RocksDB from 7.9.2 to 9.7.3 and addresses the following compatibility issues introduced by the RocksDB upgrade:
- Removal of AccessHint: The AccessHint class was completely removed in RocksDB 9.7.3. This required removing all import statements, variable declarations, method parameters, method return types, and static method calls related to AccessHint in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapterTest.java Unused methods are removed in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java
- Removal of NO_FILE_CLOSES: The NO_FILE_CLOSES metric was also removed in RocksDB 9.7.3. The calculation for numberOfOpenFiles in RocksDBMetricsRecorder.java has been adjusted to now track the total number of file opens since the last reset. The previous calculation, which subtracted NO_FILE_CLOSES from NO_FILE_OPENS, is no longer possible. The reason RocksDB removed NO_FILE_CLOSES seems to be that it did not properly work: https://github.com/search?q=repo%3Afacebook%2Frocksdb+NO_FILE_CLOSES&type=issues
- Removal of methods related to compressed block cache configuration in BlockBasedTableConfig
- Change of the signature of org.rocksdb.Options.setLogger()

In document the shell command base dir is in Kafka, so we should make all command is bin/<tools>.sh
In kafka repo doesn't have controller_static.properties this file, this would misunderstanding user, I change to use controller.properties

Also remove confusing comment related to connect & Java 17 from build.gradle.
I also updated KIP-1013 to note the implications of KIP-1032.
Reviewers: Chia-Ping Tsai <chia7712@gmail.com>
Included in this change:
1. Remove deprecated protocol api versions from json files.
3. Remove fields that are no longer used from json files (affects ListOffsets, OffsetCommit, DescribeConfigs).
4. Remove record down-conversion support from KafkaApis.
5. No longer return `Errors.UNSUPPORTED_COMPRESSION_TYPE` on the fetch path[1].
6. Deprecate `TopicConfig. MESSAGE_DOWNCONVERSION_ENABLE_CONFIG` and made the relevant
configs (`message.downconversion.enable` and `log.message.downcoversion.enable`) no-ops since
down-conversion is no longer supported. It was an oversight not to deprecate this via KIP-724.
7. Fix `shouldRetainsBufferReference` to handle null request schemas for a given version.
8. Simplify producer logic since it only supports the v2 record format now.
9. Fix tests so they don't exercise protocol api versions that have been removed.
10. Add upgrade note.
Testing:
1. System tests have a lot of failures, but those tests fail for trunk too and I didn't see any issues specific to this change - it's hard to be sure given the number of failing tests, but let's not block on that given the other testing that has been done (see below).
3. Java producers and consumers with version 0.9-0.10.1 don't have api versions support and hence they fail in an ungraceful manner: the broker disconnects and the clients reconnect until the relevant timeout is triggered.
4. Same thing seems to happen for the console producer 0.10.2 although it's unclear why since api versions should be supported. I will look into this separately, it's unlikely to be related to this PR.
5. Console consumer 0.10.2 fails with the expected error and a reasonable message[2].
6. Console producer and consumer 0.11.0 works fine, newer versions should naturally also work fine.
7. kcat 1.5.0 (based on librdkafka 1.1.0) produce and consume fail with a reasonable message[3][4].
8. kcat 1.6.0-1.7.0 (based on librdkafka 1.5.0 and 1.7.0 respectively) consume fails with a reasonable message[5].
9. kcat 1.6.0-1.7.0 produce works fine.
10. kcat 1.7.1 (based on librdkafka 1.8.2) works fine for consumer and produce.
11. confluent-go-client (librdkafka based) 1.8.2 works fine for consumer and produce.
12. I will test more clients, but I don't think we need to block the PR on that.
Note that this also completes part of KIP-724: produce v2 and lower as well as fetch v3 and lower are no longer supported.
Future PRs will remove conditional code that is no longer needed (some of that has been done in KafkaApis,
but only what was required due to the schema changes). We can probably do that in master only as it does
not change behavior.
Note that I did not touch `ignorable` fields even though some of them could have been
changed. The reasoning is that this could result in incompatible changes for clients
that use new protocol versions without setting such fields _if_ we don't manually
validate their presence. I will file a JIRA ticket to look into this carefully for each
case (i.e. if we do validate their presence for the appropriate versions, we can
set them to ignorable=false in the json file).
[1] We would return this error if a fetch < v10 was used and the compression topic config was set
to zstd, but we would not do the same for the case where zstd was compressed at the producer
level (the most common case). Since there is no efficient way to do the check for the common
case, I made it consistent for both by having no checks.

This PR covers all the docs for KIP-1112, including the new config and a note about the new APIs in the 4.0 section of the upgrade guide.
This also fixes/updates some unrelated parts of the upgrade guide that were out-of-date, such as the broker compatibility matrix

This PR introduces the DescribeGroups v6 API as part of KIP-1043. This adds an error message for the described groups so that it is possible to get some context on the error. It also changes the behaviour for when the group ID cannot be found but returning error code GROUP_ID_NOT_FOUND rather than NONE.

Documents current ApiVersions fallback mechanism
The broker behaviour when it receives an ApiVersionsRequest ahead of it's supported versions is useful to know as an implementor/manipulator of the protocol.
The behaviour contradicts a point documented in the protocol guide. In the fallback case the protocol version of the response is different from the protocol version of the request.
Also spotted a couple of dead links in the table of contents

This PR implement KIP-1011, kafka-configs.sh now uses incrementalAlterConfigs API to alter broker configurations instead of the deprecated alterConfigs API, and it will fall directly if the broker doesn't support incrementalAlterConfigs.
