This allows you to simply run `vagrant up` to get a 3 node HA cluster. * Creates a dynamic inventory and uses the inventory/group_vars/all.yml * commented lines in inventory.example so that ansible doesn't try to use it. * added requirements.txt to give easy way to install ansible/ipaddr * added gitignore files to stop attempts to save unwated files * changed `Check if kube-system exists` to `failed_when: false` instead of `ignore_errors`
