Use presets to be independent from the package.json

git-repo-info seems to be the solution. We need to figure out if it fullfills all our needs

To be independent from the package.json we need to:

• Add a CLI option --preset=node when you want to be based on a package.json
• Create a module presets/node-preset
• Preset module has a default exported function that must return an object containing all necessary information extracted (ex: name, version)

In addition, all repository information must be independent from the preset, and only based on the git local. To do it we recommend to use:

• Get the remote URL with: https://github.com/sindresorhus/git-remote-origin-url
• Get the hosted git info (bug, url...) from the remote URL: https://github.com/npm/hosted-git-info
