Make it easy to add your own advice

[soulgalore]

One thing that is missing is that we should make it super easy to add your own advice. It would be cool that you can do it using the CLI standalone but also for other tools that uses the coach (sitespeed.io at the moment).

In sitespeed.io we get coaches advice and run them together with timings from Browsertime. We should add an alternative to add your own advice + add your own category.

@soulgalore can you give me a small example of how you expect it in cli?

[soulgalore]

Well, this isn't super easy, but I think the way it could work would be to point out a new advice following the same structure as today:

--advice dom/performance/newPerfromanceAdvice.js
--advice har/bestpractice/newBestPractice.js

The bad is that you need to know the current structure. but it will make it easier to implement.

What do you feel about it @sumeetrohra or do you have another idea?

[sumeetrohra]

I think something like this would be better
--harAdvice newBestPractice.js
--domAdvice newPerformanceAdvice.js
difficult to implement but a better solution, I guess...

[soulgalore]

That would work but we will miss what category it will use? So we need find a clean way to add that too.
