Allow access to [parent] variable

[natew]

I'd really want access to the name of the parent require. So if I require a module bootstrap and it does:

require('abc.css')

I can then control the output of that file and have it be:

somedir/bootstrap/abc.css

I'd imagine it's something like:

?name=somedir/[parent]/[name].css

Another thing that would be helpful is naming based on the parent file as well as parent module. So maybe:

• [parentFile]
• [parentModule]

@natew we use https://github.com/webpack/loader-utils#interpolatename for interpolate filename. What mean parent*? How we can determinate parent?
