Describe the feature

As a developer I want to have a possibility to execute scripts before install is called, so I can resolve configuration, workspace links and so on.

As an example I have repository which I am extending, but it has a dependency via workspace. I can easily solve it if I would be able to switch workspace to registry version which can be done with external script. Same might go for set up of .npmrc.
