Flavio Percoco c2c3a205a9 'Persist' __getattr__ results
This patch adds a new decorator that helps creating 'cachable'
__getattr__ methods. The decorator sets the returned value as an
attribute of the instance.

The patch also decorates `Pipeline`'s __getattr__ method

Implements blueprint storage-pipeline
