Release new lambda image - Two important changes

[mooyoul]

There's new updates to lambda:

1. Now lambda supports function execution up to 15 minutes!
2. Now Node.js 8.10 Runtime supports any Promise implementations! (Relevant Issue: AWS Lambda Node 8.10 Runtime Support aws/aws-xray-sdk-node#27)

@mooyoul the images already support arbitrary execution times. Set the AWS_LAMBDA_FUNCTION_TIMEOUT env variable to whatever you'd like. I'll probably keep the default at 300 seconds so that it doesn't break any existing users expectations.

Updating the nodejs8.10 image now

Done – thanks for the heads up! 👍
