Alan Orth 6ccfdb99fa roles/nginx: Enable OCSP stapling
Reduces round trip time for clients. Note: I am using a certificate
chain in the `ssl_certificate' directive, so as I understand it, I
don't need to use an explicit trusted intermediate + root CA cert
with the `ssl_trusted_certificate' option. See the nginx docs for
more[0]. Addresses GitHub Issue #5.

Seems to be working, test with:

    $ openssl s_client -connect mjanja.ch:443 -servername mjanja.ch -tls1 -tlsextdebug -status

Look for "OCSP Response" with "Cert Status: good".

# nginx does not auto-rotate session ticket keys: only a HUP / restart will do so and
# when a restart is performed the previous key is lost, which resets all previous
# sessions. The fix for this is to setup a manual rotation mechanism:
# http://trac.nginx.org/nginx/changeset/1356a3b9692441e163b4e78be4e9f5a46c7479e9/nginx
#
# Note that you'll have to define and rotate the keys securely by yourself. In absence
# of such infrastructure, consider turning off session tickets:
ssl_session_tickets off;
# enable SPDY header compression
spdy_headers_comp 6;
# Enable this if you want HSTS (recommended, but be careful)
