### Current Behavior

In AWS, DescribeSubnet Response returns:
```
<?xml version="1.0" encoding="UTF-8"?>\n
    <Response>
        <Errors>
            <Error>
                <Code>InvalidSubnetID.NotFound</Code>
                <Message>The subnet ID \'test\' does not exist</Message>
            </Error>
        </Errors>
    <RequestID>f6d041c1-1c96-4720-af30-77745504e2ba</RequestID>
</Response>
```

whereas localstack returns:
```
<?xml version=\'1.0\' encoding=\'utf-8\'?>\n<Errors xmlns="http://ec2.amazonaws.com/doc/2016-11-15">
    <Error>
        <Code>InvalidSubnetID.NotFound</Code>
        <Message>aaThe subnet ID \'vpc-test\' does not exist</Message>
    </Error>
    <RequestID>EADJHWMM796CI5FT10XGFMGOXIPCBAHBWINMV0HR6SKBRODGCU5J</RequestID>
</Errors>

```

### Expected Behavior

It should return correct response structure. It causes terraform to complain.

### How are you starting LocalStack?

Custom (please describe below)

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

    make start

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

     awslocal ec2 describe-subnets --subnet-ids vpc-test --debug


### Environment

```markdown
- OS: M1 MacOS
- LocalStack: 1.0.2.dev
```


### Anything else?

Probably `call_moto` function in `localstack/services/moto.py` is changing the error code structure.
"status_code": response.status_code,
        "context": {
            "operation_name": operation.name,
        },
    }
    if response_dict["status_code"] >= 301:
        response_dict["body"] = response.data
    elif operation.has_event_stream_output:
        
        response_dict["body"] = _RawStream(response)
    elif operation.has_streaming_output:
        
        response_dict["body"] = _ResponseStream(response)
    else:
        response_dict["body"] = response.data
    factory = ResponseParserFactory()
    if response.content_type and response.content_type.startswith("application/x-amz-cbor"):
        
        factory.set_parser_defaults(
            timestamp_parser=_cbor_timestamp_parser, blob_parser=_cbor_blob_parser
        )
    parser = factory.create_parser(operation.service_model.protocol)
    parsed_response = parser.parse(response_dict, operation.output_shape)
    if response.status_code >= 301:
        
        _add_modeled_error_fields(response_dict, parsed_response, operation, parser)
    if not include_response_metadata:
        parsed_response.pop("ResponseMetadata", None)
    return parsed_response
