[scikit-learn] passing y to .transform() in pipeline

[Florin Andrei]

Any chance Pipeline will allow the target (y) to be passed to 
transformers?

I'm not talking about transforming y, although that would be nice.

I'm just talking about having y passed as an argument to transformers in 
the .transform() call. That would allow me to easily run my own target 
encoders.

Currently, not having y available during .transform() is very 
restrictive.

Thanks!
