provider/digitalocean: Add support for certificates
Besides the support for DO certificates themselves, this commit also includes: 1) A new `RandTLSCert` function that generates a valid, self-signed TLS certificate to be used in the test 2) A fix for the PEM encoding of the private key generated in `RandSSHKeyPair`: the PEM was always empty
