Add license management to Auto DevOps template

Description

License Management will help developers to know which licenses they are using because of the dependencies of their project. In this way they can check if they are using incompatible licenses.

We should provide a way to auto detect the licenses used, and to list them to users.

Proposal

Integrate LicenseFinder (https://github.com/pivotal/LicenseFinder) in Auto DevOps to provide automatic license detection for dependencies.

It supports the following languages/packagemanagers:

Project Type	Package Manager
Ruby Gems	bundler
Python Eggs	pip
Node.js	npm
Bower	bower
Nuget	nuget
Godep	Godep
Go workspace	Go lang
Go submodules	Go lang
Java	maven
Java	gradle

The output of the report should be saved as an artifact, so it can be consumed easily.
