Sync global gitignore to drupal-vm

[chrisarusso]

It would be a nice feature either as part of config or in an automated way to sync the global gitignore file (often at ~/.gitignore_global) from the host machine to the vm. If you're using PHPStorm on a project for example, and you've configured your host machine's global gitignore file to ignore .idea/ you'll see that a git status in the projec on the drupal-vm asks you if you want to add the gitignore file

I'd be happy to just add .idea to https://github.com/geerlingguy/drupal-vm/blob/master/.gitignore :)

That'll do for this specific scenario. I'm happy to submit a PR for it if you'd like. I'm also happy to look into a more robust solution that would either allow you to define it in configuration, or would port over your host global git config file 👍
