Running OpenSearch Benchmark with AWS Signature Version 4

OpenSearch Benchmark supports AWS Signature Version 4 authentication. To run Benchmark with Signature Version 4, use the following steps:

Set up an IAM user and provide it access to the OpenSearch cluster using Signature Version 4 authentication.

Set up the following environment variables for your IAM user:

OSB_AWS_ACCESS_KEY_ID=<<IAM USER AWS ACCESS KEY ID>
OSB_AWS_SECRET_ACCESS_KEY=<IAM USER AWS SECRET ACCESS KEY>
OSB_REGION=<YOUR REGION>
OSB_SERVICE=aos

Customize and run the following execute-test command with the --client-options=amazon_aws_log_in:environment flag. This flag tells OpenSearch Benchmark the location of your exported credentials.
```
opensearch-benchmark execute-test \
--target-hosts=<CLUSTER ENDPOINT> \
--pipeline=benchmark-only \
--workload=geonames \
--client-options=timeout:120,amazon_aws_log_in:environment \
```
