AwsS3BlobStorage wants to create a new bucket on read.

[AntMaster7]

I want to read an object from an S3 storage with ReadBytesAsync. However, I get an exception saying that I am not authorized to perform create-bucket. Why do I need that permission for reading?

Edit: I found the issue in the implementation. The method GetClientAsync in AwsS3BlobStorage makes a PutBucket request:

Why does it do that? It should at least check if the bucket already exists.

You can fix it like so:

private async Task<AmazonS3Client> GetClientAsync() {
    if (!_initialised) {
        var bucketExists = await AmazonS3Util.DoesS3BucketExistV2Async(_client, _bucketName);
        if (!bucketExists)  {
            var request = new PutBucketRequest { BucketName = _bucketName };

            await _client.PutBucketAsync(request).ConfigureAwait(false);
        }

        _initialised = true;
    }

    return _client;
}

I can do a PR if you want?
