[AZINTS] migrate event hub forwarder to model v4

[ava-silver]

What does this PR do?

Updates to the v4 model, which requires us to explicitly import @azure/functions, and also now deploy via zip with a remote build. Open to discuss how we want to store the deploy.zip for future maintainability.

Worth noting that this is a breaking change since customers can no longer edit in the portal.

Also consolidated the arm templates into just the eventhub_log_forwarder templates since the powershell scripts are redundant and we don't need to embed the content.

Motivation

node azure functions v3 model is disallowed, we need to migrate to model v4.

Testing Guidelines

Tested by deploying the arm template in the portal:

Test using:

Update the sub template links to point from master to refs%2Fheads%2Fava.silver%2Fazints%2Fmigrate-event-hub-forwarder-to-model-v4, and then:

and paste in for the function package uri parameter:

Additional Notes

We'll need to update the documentation since that will no longer be up to date.

I'll make a follow-up PR for that once we merge these changes.

Additionally, we'll need to update the blob forwarder as well since that will also be out of date.
