@jonathantyng-amp, before I do a full review, could you help me understand what this task does, how long it takes, and when you typically run it? (Development? Release? What about minified vs. unminified builds?)

Our browserify configs are currently fragmented (I'm in the process of trying to consolidate it), so I'd like to avoid further fragmentation if possible.

@rsimha
Context: amp-analytics uses ~70 vendor configs that are currently all compiled into the bundle. We want to separate these out to lazy load them instead. As part of this process we want to convert each vendor config into its own JSON file.

This gulp task converts the current vendor configs into their own JSON file, placing the files into /extensions/amp-analytics/0.1/vendors/. This gulp task will only be run in the next several weeks temporarily while we run some AB tests to make sure the vendor configs stay in sync. After the AB tests are complete, we will permanently commit the JSON files and this gulp task will not be needed anymore.

This task will be run in the release process and runs in ~3 sec

Thanks for the detailed explanation! Since this is temporary, the code LGTM as written.
