This PR brings 2 changes:

  • Upgrade to AWS SDK 1.10.69
  • Add repositories.s3.use_throttle_retries setting

Upgrade to AWS SDK 1.10.69

Release notes highlights from 1.10.33 for the SDK

  • Moving from JSON.org to Jackson for request marshallers.
  • The Java SDK now supports retry throttling to limit the rate of retries during periods of reduced availability. This throttling behavior can be enabled via ClientConfiguration or via the system property "-Dcom.amazonaws.sdk.enableThrottledRetry".
  • Fixed String case conversion issues when running with non English locales.
  • AWS SDK for Java introduces a new dynamic endpoint system that can compute endpoints for services in new regions.
  • Introducing a new AWS region, ap-northeast-2.
  • Added a new metric, HttpSocketReadTime, that records socket read latency. You can enable this metric by adding enableHttpSocketReadMetric to the system property com.amazonaws.sdk.enableDefaultMetrics. For more information, see Enabling Metrics with the AWS SDK for Java.
  • New Client Execution timeout feature to set a limit spent across retries, backoffs, ummarshalling, etc. This new timeout can be specified at the client level or per request.
    Also included in this release is the ability to specify the existing HTTP Request timeout per request rather than just per client.

Release notes highlights from 1.10.33 for S3

  • Added support for RequesterPays for all operations.
  • Ignore the 'Connection' header when generating S3 responses.
  • Allow users to generate an AmazonS3URI from a string without using URL encoding.
  • Fixed issue that prevented creating buckets when using a client configured for the s3-external-1 endpoint.
  • Amazon S3 bucket lifecycle configuration supports two new features: the removal of expired object delete markers and an action to abort incomplete multipart uploads.
  • Allow TransferManagerConfiguration to accept integer values for multipart upload threshold.
  • Copy the list of ETags before sorting Copy the list of ETags before sorting aws/aws-sdk-java#589.
  • Option to disable chunked encoding Option to disable chunked encoding aws/aws-sdk-java#586.
  • Adding retry on InternalErrors in CompleteMultipartUpload operation. Add Default Retry on InternalError during CompleteMultipartUpload aws/aws-sdk-java#538
  • Deprecated two APIs : AmazonS3#changeObjectStorageClass and AmazonS3#setObjectRedirectLocation.
  • Added support for the aws-exec-read canned ACL. Owner gets FULL_CONTROL. Amazon EC2 gets READ access to GET an Amazon Machine Image (AMI) bundle from Amazon S3.

Release notes highlights from 1.10.33 for EC2

  • Added support for referencing security groups in peered Virtual Private Clouds (VPCs). For more information see the service announcement at https://aws.amazon.com/about-aws/whats-new/2016/03/announcing-support-for-security-group-references-in-a-peered-vpc/ .
  • Fixed a bug in AWS SDK for Java - Amazon EC2 module that returns NPE for dry run requests.
  • Regenerated client with new implementation of code generator.
  • This feature enables support for DNS resolution of public hostnames to private IP addresses when queried over ClassicLink. Additionally, you can now access private hosted zones associated with your VPC from a linked EC2-Classic instance. ClassicLink DNS support makes it easier for EC2-Classic instances to communicate with VPC resources using public DNS hostnames.
  • You can now use Network Address Translation (NAT) Gateway, a highly available AWS managed service that makes it easy to connect to the Internet from instances within a private subnet in an AWS Virtual Private Cloud (VPC). Previously, you needed to launch a NAT instance to enable NAT for instances in a private subnet. Amazon VPC NAT Gateway is available in the US East (N. Virginia), US West (Oregon), US West (N. California), EU (Ireland), Asia Pacific (Tokyo), Asia Pacific (Singapore), and Asia Pacific (Sydney) regions. To learn more about Amazon VPC NAT, see New - Managed NAT (Network Address Translation) Gateway for AWS
  • A default read timeout is now applied when querying data from EC2 metadata service.

Add use_throttle_retries repository setting

Defaults to false (AWS SDK default value).
If anyone is having trouble, you could enable it with repositories.s3.use_throttle_retries: true in elasticsearch.yml file or set it per repository.

Shouldn't this be set independently from the maxRetries setting? I think the default retry policy is 3 and users might want to throttling this too event if the max_retries is not set in the repository settings.

I initially wrongly put this setting under `cloud.aws.s3.` prefix which does not make sense. It should be placed at the same place as `max_retries`.

Also applied @tlrx comments. We should set this even if max_retries is not set (when using default values).

Also added some documentation about this setting.

@tlrx I added new commits. I also changed the title and the description of the PR.


Note that you can define S3 repository settings for all S3 repositories in `elasticsearch.yml` configuration file.
They are all prefixed with `repositories.s3.`.

Today we are registering repository settings when `S3RepositoryPlugin` starts:

```java
        settingsModule.registerSetting(S3Repository.Repository.KEY_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.SECRET_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.BUCKET_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.ENDPOINT_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.PROTOCOL_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.REGION_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.SERVER_SIDE_ENCRYPTION_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.BUFFER_SIZE_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.MAX_RETRIES_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.CHUNK_SIZE_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.COMPRESS_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.STORAGE_CLASS_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.CANNED_ACL_SETTING);
        settingsModule.registerSetting(S3Repository.Repository.BASE_PATH_SETTING);
```

We don't need to register those settings as they are repository level settings and not node level settings.

Closes elastic#18945.

# AWS Release Notes

From 1.10.69 (see elastic#17784), here are the most important updates:

## Minor 1.10 releases:

* Amazon S3	Added support for a new configuration named BucketAccelerateConfiguration which supports faster uploads/downloads to S3 buckets.
* Adding several missing throttling error codes for API Gateway and S3.
* Amazon S3	Introducing a new version of the ListObjects (ListObjectsV2) API that allows listing objects with a large number of delete markers.

## 1.11:

AWS SDK for Java:

* Improved URL encoding for REST clients.
* Dropped usage of Json.org library in favor of Jackson.
* Updated retry policies to include jitter during backoffs.
* Generate output POJOs for all operations.
* Renamed the aws-java-sdk-flow-build-tools-{sdkversion}.jar to aws-swf-build-tools-1.0.jar. The jar is also available in Maven.

AWS SDK for Java - Amazon S3:
* Added support to return the part count of an object in object metadata. You can also download a part by setting part number in GetObjectRequest.
* TransferManager supports parallel downloads for multipart objects.
* Default to Signature Version 4 signing process in all regions.

Apache HttpClient upgraded to 4.5.2

# Jackson update

Note that [Jackson has been updated at some point](https://github.com/aws/aws-sdk-java/blob/master/pom.xml#L115) but as we don't use dependency management anymore it has never been updated and we did not notice.

So I updated:

* jackson-databind to 2.6.6.
* jackson-annotations to 2.6.0.

That being said, I'm unsure if we should better use `${versions.jackson}` instead.

# Functional changes

For `repository-s3` plugin, this new version of the AWS SDK now sets Throttle Retries (overridable by `use_throttle_retries`) to `true` by default instead of `false` previously.

# Security manager issues

Tests are failing on `repository-s3` plugin with:

```
