Update nginx cipher suite and TLS protocols
Use latest Mozilla "intermediate" TLS settings. This configuration
works on (at least) Ubuntu 18.04 and Debian 10.

See: https://ssl-config.mozilla.org/#server=nginx&server-version=1.17.2&config=intermediate&openssl-version=1.1.1

group_vars/all: Disable TLS cipher suites using Triple DES
An attack on Triple DES was recently published[0]. It's not a very
high severity attack but the fact is that Triple DES is very old
and there are much better ciphers to use, like AES and ChaCha20.

I logged the ciphers that were negotiated on all of my vhosts over
a period of 72 hours and there were zero occurences of Triple DES,
so I am removing it, as suggested by the authors of the attack as
well as OpenSSL[1].

Downgrade TLS configuration to Mozilla's "intermediate" spec
From looking at the list of clients who would be allowed to connect
when using the "modern" spec, I think I'd be doing more harm than
good to use that config right now...
