Evaluate GitLab Serverless for Security Automation

This is mostly a placeholder issue to link to the original issue on the gl-security team.

Problem Statement

Security Automation is interested in dogfooding GitLab Serverless

Status

Following a discussion with @adietrich the key takeaways are:

• they use serverless approaches for ChatOps mostly
• they often run their tasks as scheduled jobs. The scheduled jobs are usually initiated from Google scheduler, not GitLab, as our CI is not stable for them.
• secrets management is a crucial question for them
• they don't run K8s clusters

Given these requirements, our solution might not add much value to them at this stage.
