Abilities to use lr-mobile-config.js and lr-desktop-config.js

[Yivan]

Hello,

First I would like to say this extension is really great, it is very convenient for us to be able to run lighthouse tests together with sitespeed.io test, and having the possibility to consult them in just one panel (html reports or grafana).

Actually only two profiles can be extended: default-config.js and full-config.js.

This issue is to sugger to add two more: lr-mobile-config.js and lr-desktop-config.js
So we can set like:

--lighthouse.extends lr-mobile

--lighthouse.extends lr-desktop

This way in combination with the --lighthouse.settings.emulatedFormFactor difference between desktop/mobile are best reflected.

I hope it makes sense.

Thanks!
Best regards

After some further test (please see: #48), adding the possibility to use those 2 new profiles will be a really great things to achieve better result in same line of the results of Google Page Speed Insight.

In the meantime, is there a way to use custom profile or add those two file prrofile manually ? (as they are here: https://github.com/GoogleChrome/lighthouse/tree/master/lighthouse-core/config)

Thanks.

I can review and test a PR for that, it needs to be implemented on our side if I understand correctly see
