Failed integrating with AWS DAX

Hi, I am currently integrating newrelic agent into our application.

I noticed that if I use AWS DAX as a replacement of DynamoDB client, I always got an error on every DB manipulation.

const dax = new AmazonDaxClient({ region: 'us-east-1', endpoints: ['some.endpoint'] });
const dbClient = new AWS.DynamoDB.DocumentClient({ service: dax });
await dbClient.query({ ... }).promise();

Cannot read property 'host' of undefined
error: TypeError: Cannot read property 'host' of undefined
    at DocumentClient.wrapOperation (/home/ec2-user/async_worker/node_modules/@newrelic/aws-sdk/lib/dynamodb.js:64:39)
    at DocumentClient.opRecorder (/home/ec2-user/async_worker/node_modules/newrelic/lib/shim/datastore-shim.js:411:24)
    at DocumentClient.wrapper [as get] (/home/ec2-user/async_worker/node_modules/newrelic/lib/shim/shim.js:927:33)
    ...

But a regular DynamoDB client works fine.

const ddb = new AWS.DynamoDB({ region: 'us-east-1' });
const dbClient = new AWS.DynamoDB.DocumentClient({ service: ddb });
await dbClient.query({ ... }).promise();

Tried @newrelic/aws-sdk but the issue remains.

A new version of the agent has been deployed including the new version of the aws-sdk instrumentation. Please let us know if you have further issues.

@seoker The aws-sdk wasn’t rolled into the agent for auto-install until version 6.1.0. So any earlier version should avoid that.
