Limit Number of Requests

[thostetler]

I recently had an issue during our build process, volo was getting stuck on:

volo add -f -nostamp jquery/qunit/v1.14.0#. <-- Endless loop, eventually exceeds rate_limit

Realized that it's making tons of requests, blowing through my rate limit within a minute or so.
The fix ended up being jquery --> qunitjs.

volo add -f -nostamp qunitjs/qunit/v1.14.0#. <-- This works fine, 1 request

But I was wondering if it's a bug that it doesn't recognize that the Url is broken, or if there is an option for limiting the number of requests before it will move on/throw error.
