Migrate to 2nd gen functions

[eli1stark]

Cloud Functions (2nd gen) is Google Cloud's next-generation Functions-as-a-Service offering. Built on Cloud Run and Eventarc, Cloud Functions (2nd gen) brings enhanced infrastructure and broader event coverage to Cloud Functions, including:

• Longer request processing times: Run longer-request workloads such as processing large streams of data from Cloud Storage or BigQuery.
• Larger instance sizes: Run larger in-memory, compute-intensive, and parallel workloads.
• Improved concurrency: Handle multiple concurrent requests with a single function instance to minimize cold starts and improve latency.
• Traffic management: Split traffic between different function revisions or roll a function back to a prior version.
• Eventarc integration: Native support for Eventarc triggers, bringing all 90+ event sources supported by Eventarc to Cloud Functions.
• Broader CloudEvents support: Support for industry-standard CloudEvents in all language runtimes, providing a consistent developer experience.

With 2nd gen we are also able to minimize cold starts with CPU boost.
