The broker observer should not read update voter set timer value when
polling to determine its backoff, since brokers cannot auto-join the
KRaft voter set. If auto-join or kraft.version=1 is not supported,
controller observers should not read this timer either when polling.
The updateVoterSetPeriodMs timer is not something that should be
considered when calculating the backoff returned by polling, since this
timer does not represent the same thing as the fetchTimeMs timer.

Previously, at the default log level, you could only see logs that the

it was logged at debug.

Add the `controller.quorum.auto.join.enable` configuration. When enabled
with KIP-853 supported, follower controllers who are observers (their
replica id + directory id are not in the voter set) will:
- Automatically remove voter set entries which match their replica id
but not directory id by sending the `RemoveVoterRPC` to the leader.
- Automatically add themselves as a voter when their replica id is not
present in the voter set by sending the `AddVoterRPC` to the leader.

### Summary
Adds comprehensive test coverage for the StorageTool format command
feature validation, including tests for valid feature overrides, invalid
feature detection, and multiple feature specifications. Also adds debug
output to help with troubleshooting format operations.
### Changes Made
#### Test Coverage Improvements
- **`testFormatWithReleaseVersionAndFeatureOverride()`**: Tests that
feature overrides work correctly when specified with `--feature` flag
- **`testFormatWithInvalidFeatureThrowsError()`**: Tests error handling
for unsupported features
- **`testFormatWithMultipleFeatures()`**: Tests multiple feature
specifications in a single format command
#### Debug Output Enhancement
- **Formatter.java**: Added debug output to print bootstrap metadata
during format operations
- Helps with troubleshooting format issues by showing the complete
bootstrap metadata being written
- Improves visibility into what features and configurations are being
applied
#### Test Updates
- **FormatterTest.java**: Updated existing tests to account for the new
debug output\

In the current implementation, some delayed share fetch operations get
trapped in the delayed share fetch purgatory when the partition
leaderships change during share consumption. This is because there is no
check in code to make sure the current broker is still the partition
leader corresponding to the share partitions. So, when leadership
changes, the share partitions cannot be acquired, because they have
already been fenced, and tryComplete returns false. Although the
operatio does get completed when the timer expires for it, but it is too
late by then, and the operation get stuck in the watchers list waiting
for it to get purged when estimated operations increase to more than
1000. This Pr resolves this by adding the required check so that if
partition leadership changes, then the delayed share fetches waiting on
it gets completed instantaneously.

- If a `ShareConsumer` constructor failed due to any exception, then we
call `close()` in the catch block.
- If there were uninitialized members accessed during `close()`, then it
would throw a NPE. Currently there are no null checks, hence we were
attempting to use these fields during `close()` execution.
- To avoid this, PR adds null checks in the `close()` function before we
access fields which possibly could be null.

Fixing max delivery check on acquisition lock timeout and write state
RPC failure.
When acquisition lock is already timed out and write state RPC failure
occurs then we need to check if records need to be archived. However
with the fix we do not persist the information, which is relevant as
some records may be archived or delivery count is bumped. The
information will be persisted eventually.
The persister call has failed already hence issuing another persister
call due to a failed persister call earlier is not correct. Rather let
the data persist in future persister calls.

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.

*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.
