Add a tool to parse metrics output and extract URLs within ranges by page view count

[dacharyc]

We have some internal tooling that outputs metrics with a specific format, similar to:

Page,Page Subsite,Measure Names,Measure Values,Min. Aux
www.example.com/docs/get-started/create-project/,Docs,Pageviews,14,1
www.example.com/docs/get-started/install/,Docs,FT Within 1 Day,2145,1

This tool can take the csv input and provide an output csv that:

• Filters out irrelevant rows (rows that aren't related to Page views)
• Capture the rows based on the input range, or 1-250 - i.e. "Top 250" if no input range is provided
• Outputs just the rank and URL in ascending order for use in other contexts

This lets us get "top 50" or "top 250", or later, when we're ready, "250-300" or whatever that looks like.

I'll use the output with the Audit CLI to extract additional info to help us scope work related to these pages.

The tool creates an output csv with no headers like:

10,www.example.com/docs/get-started/install/
14,www.example.com/docs/get-started/create-project/

LGTM! Just a minor comment.

Does it make sense to print a success message when a run completes without an error?

[dacharyc]

I had it omit a success message since I thought we might use it in a pipeline - i.e. create this output and then use the output as the input in a next step. But if you'd prefer a success message, it's easy to add one!

[krollins-mdb]

Nah, I wasn't totally sure if this was going to end up in a pipeline, but thought it might. A success message may be confusing in that case, so let's keep it out. Thanks for entertaining the thought.

Nice improvements with config file. I love config files. 😆
