Update from functions to functions2

[a5chin]

Summary

The version of cloud functions written in terraform was 1st gen, so I updated it to 2nd gen. google_cloudfunctions_function->google_cloudfunctions2_function

Why you need this PR

As shown below, the 2nd generation is recommended over the 1st generation in Google Cloud.

We recommend that you choose Cloud Functions (2nd gen) for new functions wherever possible. However, we plan to continue supporting Cloud Functions (1st gen).

What I did

The following 2 files have been updated.

• autoscalse/terraform/modules/autoscaler-functions/main.tf
• autoscalse/terraform/modules/forwarder/main.tf

FYI

Already tested with our products.
