Document NewRelic Lambda integration and clean up API keys

[jimleroyer]

Description

As an ops lead, I want to know how the lambda reporting integration was done in between NewRelic and AWS, So that I can debug accordingly if things get broken but also recreate in for a new environment.

WHY are we building?

To know what we do. To recreate similar environments.

WHAT are we building?

Documentation and cleaning up the API keys that are not used by this integration.

VALUE created by our solution

To recreate environment properly and clean house.

Acceptance Criteria

• [ ] Document how NewRelic reports lambda data back, how this was installed, how to update, which API keys are used, etc..
• [ ] Make sure to tie this previous documentation to our BCP.
• [ ] Clean up unused API keys once we identify the ones that are used by this integration and other known access.

QA Steps

• [ ] Review by the team of the documentation.

Additional information

The integration was done within the context of this task, where links are provided on the installation. The newrelic-lambda-cli was used and we should be able to reinstall easily if necessary.
