Running Flex Serverless - Azure Function App?

[NickAtTyl]

Is your feature request related to a problem? Please describe.

This is a Function App guide request.
We have an Azure-only mandate and would like to run Flex on an Azure Function App, which is similar to AWS Lambda.

Feature Description

It should be possible to run a Go app like Flex on Azure serverless by using a custom handler, but right now there are no guides / documentation available like there is for AWS Lambda.

Existing documentation

Microsoft publishes documentation on setting up a custom Go handler for Azure Function Apps.

Additional context

AWS Lambda has an example here: https://github.com/newrelic/nri-flex/tree/master/examples/lambdaExample

Priority

Must Have

We cannot use a VM, K8s or other Cloud provider due to existing lock-in policies. I understand this is our own company imposing this, but we have to get this working on Azure Function Apps or we cannot use New Relic Flex here.
