Implement Bootstrap Deploy

Implement #1
Let me rephrase my question: How can we include both keys below into the same file?
- https://github.com/rxaviers.keys
- https://github.com/nikolavidovic.keys

Would the below do it? I guess not.

    - name: Save public key to authorized keys (1/2)
      get_url: url=https://github.com/rxaviers.keys dest=/root/.ssh/authorized_keys mode=700

    - name: Save public key to authorized keys (2/2)
      get_url: url=https://github.com/nikolavidovic.keys dest=/root/.ssh/authorized_keys mode=700
