S3EncryptionClientException: Re-subscription is not supported during Multipart Upload retry (InputStream source)

### Problem:
We are encountering a critical failure when performing a high-level Multipart Upload (putObject) using the AWS S3 Encryption Client. The operation fails specifically during SDK automatic retry attempts triggered by network latency.

Suppressed: software.amazon.awssdk.core.exception.SdkClientException: Request attempt 1 failure: Unable to execute HTTP request: Write timed out
```
Environment:

Component: AWS S3 Encryption Client (High-level Multipart Upload)
SDK Version: software.amazon.encryption.s3: "3.3.5", software.amazon.awssdk: "2.31.67"
**Network Conditions: Outgoing traffic on port 443 is throttled to 1 Mbps using tc rules.**
Data Source: InputStream (Strict requirement)

Observed behaviour:
1. Due to the 1 Mbps throttle, the upload of a part occasionally times out or disconnects.
2. The AWS SDK correctly identifies the failure and attempts a retry (indicated by SDK Attempt Count: 2 in logs).
3. The retry logic fails immediately because the S3 Encryption Client is unable to reset or re-subscribe to the underlying InputStream.
4. Code snippets:
```
S3EncryotionClient:
S3EncryptionClient
.builder()
.credentialsProvider(...)
.wrappedClient(unencryptedS3Client)
.dualstackEnabled(shouldUseDualStack)
.overrideConfiguration(clientConfigs)
.enableMultipartPutObject(enableHighLevelMultipartUpload)
.enableLegacyUnauthenticatedModes(true)
.enableLegacyWrappingAlgorithms(true)
.enableDelayedAuthenticationMode(true)
.cryptoProvider(cryptoComplyFipsProvider)
unencryptedS3Client:
S3Client
.builder()
.credentialsProvider(
credentials.getAwsV2CredentialsProvider
)
.forcePathStyle(usePathStyleAccess)
.dualstackEnabled(shouldUseDualStack)
.httpClientBuilder(httpClient)
.overrideConfiguration(clientConfigs)
.endpointOverride(s3UriEndpoint)
.region(Region.of(s3Region))
.build()
httpClient:
ApacheHttpClient
.builder()
.useIdleConnectionReaper(useApacheIdleConnectionReaper)
.maxConnections(awsConf.awsMaxConnections.get)
.connectionTimeout(Duration.ofMillis(1000000))
.socketTimeout(Duration.ofMillis(1000000))
.connectionMaxIdleTime(Duration.ofMillis(1000000))
```

### Solution:

It seems sdk is no honouring the timeouts given in httpClient and instead sdk is internally creating a wrapped async client which have its own timeout values.
The above claim is supported by the user agent value found in multipart upload request:
```
POST https://bucket-rsa-akshay-126.s3.us-west-2.amazonaws.com/5gbfile__metadata?uploads
User-Agent=[APN/1.0 Rubrik/1.0 Thor/1.0 aws-sdk-java/2.31.67 md/io#async md/http#NettyNio ...]

while on the other hand head request headers:

HEAD https://bucket-rsa-akshay-126.s3.us-west-2.amazonaws.com/5gbfile
Host=[bucket-rsa-akshay-126.s3.us-west-2.amazonaws.com], User-Agent=[APN/1.0 Rubrik/1.0 Thor/1.0 aws-sdk-java/2.31.67 md/io#sync md/http#Apache...]
```

if async client is mandatory for s3 client it should be restricted if not then encryption client should always use the ApacheHttpClient.
