Add the possibility to change the default configuration when deployn on Netlify

[Giuliano1993]

at the moment Netlify options sent to API to deploy a project are somehow hardcoded: the options are mostly in the direction of a vue project. But we need to have the possibility to change some of them, specifically:

{
      "branch": repo['default_branch'],
      "cmd": "npm run build",
      "dir": "dist/",
      "private": false,
}

these are mostly default commands and directives but could change at times,
branch: is the branches to deploy when it has got pushes or PR
**cmd: ** is the build command
dir is the directory where the built projects is
private check for the private repositories

We should ask some question thanks to inquirer in order to allow this value to be set (the values should default to the ones already in)
