Support KNP Menu

[tacman]

AdminLTEBundle supported KnpMenu, which was nice. It's a powerful library.

I see that the key for knp_menu support is in the config, but if it's enabled it fails, because knp-menu.yml is missing from the config.

I've added that file, but of course the rendering doesn't work. @kevinpapst , is that something you can bring over from the old bundle? Especially since it looks like we should have vertical menu support soon.

If someone wants to provide the code via PR 🎉 I don't mind testing and merging it.
It seems to be a well known and wide spread package...
But I don't use it and have no need for it, so I will not put my time into it.

But the question is, can we add this without add knp menu as dependency?

I think it's:)

Yes, would go into require-dev

Edit: ups, you were quicker
