Subject: Move /etc/ssl/private/dhparams.pem to /etc/ssl/dhparams.pem and make
 it public.

Ideally we we should also increase the Diffie-Hellman group size from
2048-bit to 3072-bit, as per ENISA 2014 report.

    https://www.enisa.europa.eu/publications/algorithms-key-size-and-parameters-report-2014

But we postpone that for now until we are reasonably certain that older
client won't be left out.
