S3:SelectObjectContent does not support versionId

Question

S3:SelectObjectContent should behave similar to S3:GetObject, Except it does select content from file. Why it does not support VersionId ? Do we have a plan to add VersionId support. This can enable many usecases.

Hi,

Although it is not described in the documentation, according to the following [AWS GitHub repository issue](https://github.com/aws/aws-sdk-java/issues/2357#issuecomment-644896382), you can specify the versionId as a custom query param in the request:

```
SelectObjectContentRequest selectRequest = new SelectObjectContentRequest()
    .withBucketName(BUCKET)
    .withKey(KEY)
    .withExpression("SELECT count(*) from S3Object s")
    .withExpressionType(ExpressionType.SQL)
    .withInputSerialization(...)
    .withOutputSerialization(...);

selectRequest.putCustomQueryParameter("versionId", "AAA");
```

Have you tried it?
