Figure out how to enable APM on ESF

[zmoog]

I deployed ESF, and it is running smoothly, and life is good.

Now I want to enable APM to get better visibility on the lambda function execution.

According to https://www.elastic.co/guide/en/observability/master/aws-deploy-elastic-serverless-forwarder.html:

To enable Elastic APM instrumentation for your new deployment:

• Open the AWS web console
• Go to Lambda > Functions , and find and select the function the starts with serverlessrepo-.
• Go to the Configuration tab and select Environment Variables
• Add the following environment variables:

Key	Value
ELASTIC_APM_ACTIVE	true
ELASTIC_APM_SECRET_TOKEN	token
ELASTIC_APM_SERVER_URL	url

To get the required settings, log into your Elastic deployment and:

• Visit Observability > APM
• Click on Add data

Select one of the existing APM Agents and then copy and paster the secret token and server URL.
