Adds new ClientManager interface/implementation which provides on-demand
creation of synchronous and asynchronous s3 clients, s3 transfer manager,
and in close() terminates these.
S3A FS is modified to
* Create a ClientManagerImpl instance and pass down to its S3Store.
* Use the same ClientManager interface against S3Store to demand-create
the services.
* Only create the async client as part of the transfer manager creation,
which will take place during the first rename() operation.
* Statistics on client creation count and duration are recorded.
+ Statistics on the time to initialize and shutdown the S3A FS are collected
in IOStatistics for reporting.
Adds to hadoop common class
LazyAtomicReference<T> implements CallableRaisingIOE<T>, Supplier<T>
and subclass
LazyAutoCloseableReference<T extends AutoCloseable>
extends LazyAtomicReference<T> implements AutoCloseable
These evaluate the Supplier<T>/CallableRaisingIOE<T> they were
constructed with on the first (successful) read of the the value.
Any exception raised during this operation will be rethrown, and on future
evaluations the same operation retried.
These classes implement the Supplier and CallableRaisingIOE
interfaces so can actually be used for to implement lazy function evaluation
as Haskell and some other functional languages do.
LazyAutoCloseableReference is AutoCloseable; its close() method will
close the inner reference if it is set
This class is used in ClientManagerImpl for the lazy S3 Cliehnt creation
and closure.

Speed up slow tests
* TestS3AAWSCredentialsProvider: decrease thread pool shutdown time
* TestS3AInputStreamRetry: reduce retry limit and intervals

The new test TestAWSV2SDK scans the aws sdk bundle.jar and prints out all classes
which are unshaded, so at risk of creating classpath problems
It does not fail the test if this holds, because the current SDKs
do ship with unshaded classes; the test would always fail.
The SDK upgrade process should include inspecting the output
of this test to see if it has got worse (do a before/after check).
Once the AWS SDK does shade everything, we can have this
test fail on any regression

* WrappedIO methods raise UncheckedIOExceptions
*New class org.apache.hadoop.util.functional.FunctionalIO
with wrap/unwrap and the ability to generate a
java.util.function.Supplier around a CallableRaisingIOE.

- restore old outcome: no-op
- test this
- update spec
This is a critical fix for vector IO and MUST be cherrypicked to all branches with
that feature

It is now possible to provide a job ID in the maven "job.id" property
hadoop-aws test runs to isolate paths under a the test bucket
under which all tests will be executed.
This will allow independent builds *in different source trees*
to test against the same bucket in parallel, and is designed for
CI testing.
Example:
mvn verify -Dparallel-tests -Droot.tests.enabled=false -Djob.id=1
mvn verify -Droot.tests.enabled=false -Djob.id=2
- Root tests must be be disabled to stop them cleaning up
the test paths of other test runs.
- Do still regularly run the root tests just to force cleanup
of the output of any interrupted test suites.

Customer-provided-keys (CPK) configs are not allowed with non-hierarchal-namespace (non-HNS) accounts for ABFS. This patch aims to prevent ABFS initialization for non-HNS accounts if CPK configs are provided.

* parameterize the test run rather than do it from within the test suite.
* log what the committer factory is up to (and improve its logging)
* close all filesystems, then create the test filesystem with cache enabled.
The cache is critical, we want the fs from cache to be used when querying
filesystem properties, rather than one created from the committer jobconf,
which will have the same options as the task committer, so not actually
validate the override logic.

Addresses
* CVE-2024-29857 - Importing an EC certificate with specially crafted F2m parameters can cause high CPU usage during parameter evaluation.
* CVE-2024-30171 - Possible timing based leakage in RSA based handshakes due to exception processing eliminated.
* CVE-2024-30172 - Crafted signature and public key can be used to trigger an infinite loop in the Ed25519 verification code.
* CVE-2024-301XX - When endpoint identification is enabled and an SSL socket is not created with an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address.

WrappedIO.bulkDelete_PageSize() => bulkDelete_pageSize()
Makes it consistent with the HADOOP-19131 naming scheme.
The name needs to be fixed before invoking it through reflection,
as once that is attempted the binding won't work at run time,
though compilation will be happy.

Adds support for metric collection at the filesystem instance level.
Metrics are pushed to the store upon the closure of a filesystem instance, encompassing all operations
that utilized that specific instance.
Collected Metrics:
- Number of successful requests without any retries.
- Count of requests that succeeded after a specified number of retries (x retries).
- Request count subjected to throttling.
- Number of requests that failed despite exhausting all retry attempts. etc.
Implementation Details:
Incorporated logic in the AbfsClient to facilitate metric pushing through an additional request.
This occurs in scenarios where no requests are sent to the backend for a defined idle period.
By implementing these enhancements, we ensure comprehensive monitoring and analysis of filesystem interactions, enabling a deeper understanding of success rates, retry scenarios, throttling instances, and exhaustive failure scenarios. Additionally, the AbfsClient logic ensures that metrics are proactively pushed even during idle periods, maintaining a continuous and accurate representation of filesystem performance.

Applications can create a BulkDelete instance from a
BulkDeleteSource; the BulkDelete interface provides
the pageSize(): the maximum number of entries which can be
deleted, and a bulkDelete(Collection paths)
method which can take a collection up to pageSize() long.
This is optimized for object stores with bulk delete APIs;
the S3A connector will offer the page size of
fs.s3a.bulk.delete.page.size unless bulk delete has
been disabled.
Even with a page size of 1, the S3A implementation is
more efficient than delete(path)
as there are no safety checks for the path being a directory
or probes for the need to recreate directories.
The interface BulkDeleteSource is implemented by
all FileSystem implementations, with a page size
of 1 and mapped to delete(pathToDelete, false).
This means that callers do not need to have special
case handling for object stores versus classic filesystems.
To aid use through reflection APIs, the class
org.apache.hadoop.io.wrappedio.WrappedIO
has been created with "reflection friendly" methods.
