Use Ansible instead of Bash for provisioning

The deployment is not quite working, and I'm unable to test right now:
DigitalOcean is returning 503 for my requests.

As of this commit, I can run =ansible-playbook provider.yml= more than once and
it will actually be idempotent.

Notes:
- SSH fingerprint are now taken from the public key file instead of manually
supplying it in the terraform template using the =digitalocean_ssh_key=
resource;
- use Ansible instead of ad-hoc Bash scripts for provisioning the Droplets
created by Terraform;
- use the =filename.env.extension= to create the concrete files in CI;
- use the =user_data= to add the know SSH key pair to the newly created Droplet;
- add =rotate-ssh-keys.sh= utils;
