Automated security scans of flows

### Description

In a call with a prospect, they've mentioned that IT has raised concerns over the flexibility of the function node and OT being in charge of flows within their Node-RED instances. They have asked for OT to provide a full security scan of their flows to check for exposed API keys, etc.

This could be a service we offer customers automatically, a security scan that ensure secure data is not leaked in places it should not be.
