provider/digitalocean: acctest improvements

* Add SSH Keys to all droplets in tests, this prevents acctests from
   spamming account owner email with root password details
 * Add a new helper/acctest package to be a home for random string / int
   implementations used in tests.
 * Insert some random details into record tests to prevent collisions
 * Normalize config style in tests to hclfmt conventions
