[Icons] Add variation attr to icons?

[Losses]

https://material.io/tools/icons/ now provide multiple style of icons, what about adding these variation into @material-ui/icons ? Is variation a proper attr?

We are waiting on the Google team to release the new icons set #11810.

I created a repo with the new icons, we just need some tweaking to match the file structure of the google icons repository

https://github.com/saculbr/material-design-icons

some icons now have a different size from all the others (just 6 of them, you can view they here https://github.com/saculbr/material-design-icons/blob/master/index.js#L23), I can normalize them later
I think that this is a good starting point :)

@saculbr Should we update our icon generator tool to scrape https://material.io/tools/icons/ instead of using https://www.npmjs.com/package/material-design-icons?

[hexetia]

is a viable alternative while the official repository is not updated, the biggest pro to do the scrapping is to give a good experience to the devs, especially the beginners, because it's a little confusing not being able to find the site icons in the material-ui

the only con that I see in this strategy is that it will be a bit hard to know when new icons have been added, revised or removed

we can do a direct checksum in the icons source file (https://material.io/tools/icons/static/data.json) to do a temporary versioning (a good work around)

but this is not a big problem, we can go back when they update the official repository

@saculbr Really a good idea!
