Default SSH Key

Create a default id_rsa SSH key if one is not present in the repository / fork of Install Doctor

Overview

This script generates a pair of default id_rsa and id_rsa.pub keys if one is not already present on the system after the Install Doctor provisioning process completes. It also ensures the private key is only readable and writable the provisioning user.
