chore: Add experimental test analytics [CFG-2157]

[ofekatr]

• Follows CONTRIBUTING rules

What does this PR do?

• Computes analytics for the experimental test flow.
• Prints the analytics to the debug logs.
• DOES NOT send the analytics.

Where should the reviewer start?

src/lib/iac/test/v2/analytics

How should this be manually tested?

• Run snyk iac test --experimental -d
• Ensure the printed analytics are the expected ones.

Any background context you want to provide?

• The current implementation is discussed in this Notion page. The page also describes the analytics that should be computed by the experimental flow, and some ideas for more analytics information that could be useful in the future.

• Because the analytics information that we are going to compute cannot be sent over the network yet, it will be sufficient to print them to a debug logger for the time being. The information we compute must not be shared with the analytics module in the CLI.

• This feature must be implemented in snyk and not in snyk-iac-test, because when we will eventually send the analytics over the network, we must use the analytics package as implemented in the CLI.

looks good on my local run and the numbers add up.

I assume that the iac-rules-bundle-version will be added later as per comment and we didn't want to default it to empty string, etc.

What about this comment/suggestion here? do we want to add the errors here too?

@ipapast I've just added an iac-error-codes property to address it, I think it captures what the comment suggested, but please share your feedback too.

I think it's very useful, let's keep it
