From: Enrico Scholz <enrico.scholz@sigma-chemnitz.de>

This implements an 'npm cache add' like functionality but allows to
specify the key of the data and sets metadata which are required to
find the data.

It is used to cache information as done during 'npm install'.

Keyformat and metadata are nodejs version specific.
