This commit updates CI to test against Java 24 instead of Java 23 which
is EOL.
Due to Spotbugs not having released version 4.9.4 yet, we can't run
Spotbugs on Java 24. Instead, we are choosing to run Spotbugs, and the
rest of the compile and validate build step, on Java 17 for now.
Once 4.9.4 has released, we will switch to using Java 24 for this.
Exclude spotbugs from the run-tests gradle action. Spotbugs is already
being run once in the build by "compile and validate", there is no
reason to run it again as part of executing tests.

When using a connector that requires a schema, such as JDBC connectors,
with JSON messages, the current JSONConverter necessitates including the
schema within every message. To address this, we are introducing a new
parameter, schema.content, which allows you to provide the schema
externally. This approach not only reduces the size of the messages but
also facilitates the use of more complex schemas.

The PR fixes following:
1. In case share partition arrive at a state which should be treated as
final state
of that batch/offset (example - LSO movement which causes offset/batch
to be ARCHIVED permanently), the result of pending write state RPCs for
that offset/batch override the ARCHIVED state. Hence track such updates
and apply when transition is completed.
2. If an acquisition lock timeout occurs while an offset/batch is
undergoing transition followed by write state RPC failure, then
respective batch/offset can
land in a scenario where the offset stays in ACQUIRED state with no
acquisition lock timeout task.
3. If a timer task is cancelled, but due to concurrent execution of
timer task and acknowledgement, there can be a scenario when timer task
has processed post cancellation. Hence it can mark the offset/batch
re-avaialble despite already acknowledged.

Reviewers: TengYao Chi <frankvicky@apache.org>, Lan Ding
<isDing_L@163.com>
*What*
Currently when we received a top level error response in ShareFetch, we
would log the error, update the share session epoch and proceed to the
next request.
But these acknowledgements(if any) are not completed and the callback
would not have been processed.
PR aims to address this by completing these acknowledgements with the
error code from the response in this case.

`UnsupportedOperationException` when processing plugins that have
loadable classes but no ServiceLoader manifest files.
### Root Cause
Line 326 attempts to remove from an immutable `Collections.emptySet()`:
```java

### Solution
Replace `Collections.emptySet()` with `new HashSet<>()` to provide a
mutable set.

All state updater threads use the same metrics instance, but do not use
unique names for their sensors. This can have the following symptoms:
1) Data inserted into one sensor by one thread can affect the metrics of
all state updater threads.
2) If one state updater thread is shutdown, the metrics associated to
all state updater threads are removed.
3) If one state updater thread is started, while another one is removed,
it can happen that a metric is registered with the `Metrics` instance,
but not associated to any `Sensor` (because it is concurrently removed),
which means that the metric will not be removed upon shutdown. If a
thread with the same name later tries to register the same metric, we
may run into a `java.lang.IllegalArgumentException: A metric named ...
already exists`, as described in the ticket.
This change fixes the bug giving unique names to the sensors. A test is
added that there is no interference of the removal of sensors and
metrics during shutdown.

This PR adds a check to the storage tool's format command which throws a
TerseFailure when the controller.quorum.voters config is defined and the
node is formatted with the --standalone flag or the
--initial-controllers flag.
Without this check, it is possible to have two voter sets. For example,
in a three node setup, the two nodes that formatted with
--no-initial-controllers could form quorum with each other since they
have the static voter set, and the --standalone node would ignore the
config and read the voter set of itself from its log, forming its own
quorum of 1.

Fixes a bug with tiered storage quota metrics introduced in [KIP-956](https://cwiki.apache.org/confluence/display/KAFKA/KIP-956+Tiered+Storage+Quotas).
The metrics tracking how much time have been spent in a throttled state
can stop reporting if a cluster stops stops doing remote copy/fetch and
the sensors go inactive.
This change delegates the job of refreshing inactive sensors to
SensorAccess. There's pretty similar logic in RLMQuotaManager which is
actually responsible for tracking and enforcing quotas and also uses a
Sensor object.

The PR restricts the records being acquired post max-inflight limit.
Previously the max in-flight limit was only enforced while considering
the share partition for further fetches i.e. once the limit was reached
the share partition was not considered for further fetches. However,
when the records are actively released then there might be some records
being acquired post max-inflight limit. This is evident with higher
number of consumers reading from same share partition and releasing the
records.

This PR fixes an issue where the thread name shown in log messages did
not match the actual execution context. Previously, log entries
displayed the context of the newly created thread, while the logger
reflected the current executing thread. This mismatch led to confusion

- Use logger without context to not have context
- Updated log messages to explicitly describe the thread being created
- Fixed instances where the log context reflected the current thread

BrokerNotFoundException exception is unused since 2.8 Marking it
deprecated so that it can be removed in next major release.
Reviewers: Matthias J. Sax <matthias@confluent.io>
Observers may get stuck fetching from bootstrap servers even on
discovery of a leader from a fetch response.
Observers currently fetch from bootstrap servers once their fetch
timeout expires, and even on rediscovery of the leader (e.g. observer
receives fetch response indicating location of leader), observers will
not attempt to resume fetching from the leader.
This change simplifies observer polling logic to just rely on
maybeSendFetchToBestNode which takes care of the logic of selecting
either the leader or bootstrap servers as the destination based on
timeouts and backoffs.

We found that one broker's local segment on disk never get removed
forever no matter how long it stored. The disk always keep increasing.
note: Partition 2's node is the exception node.
After we trouble shooting. we find if one broker is very slow to startup
it will cause the
TopicBasedRemoteLogMetadataManager#initializeResources's fail sometime
(it meet expectation due to the server is not ready as fast). Thus it
won't stop the server so that the server still run just with some
exception log but not shutdown. It won't upload to remote for the local
so that the local segment never to deleted.
So propose the change to shutdown the broker to avoid the silence
critical error which caused the disk keep increasing forever.
