Billing Duration reported in 100ms intervals

[danPudwellUK]

Description:

When using sam local start-api the billing duration is reported in 100ms intervals

Steps to reproduce:

I used the Hello World quick start template
Run sam local start-api --port 8080
Hit the function

Observed result:

Duration: 255.59 ms Billed Duration: 300 ms

Expected result:

I would have expected billing duration to be 256ms

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

I ran it in Cloud9

I looked through the code and couldn't find anything in this repo relating to printing this out. I'm assuming its pulling this in from somewhere else so maybe an old dependency?

The "reporting" line in the output is done by RIE and fixed in this PR: aws/aws-lambda-runtime-interface-emulator#7

We have a PR to pull in the new RIE binary: #3029 but there were some issues that we haven't fully diagnosed yet. Once that PR is merged and released, this will go away.

As a note, this is purely output in the CLI. Lambda does the correct thing for billing.
