roles/nginx: Correct HSTS header in https template
...
Apparently the "always" syntax isn't used anymore (ever?), not sure
where I got it from but this definitely causes HSTS to not work.

roles/nginx: Add $request_method to nginx fastcgi_cache_key

nginx is caching HEAD requests, then when users come along and do
a GET request they get an HTTP 200 with no request body. It seems
setting fastcgi_request_methods to GET doesn't stop nginx from caching
HEADs, so for now just add the $request_method to the key.

Remove provisioning user management
...
It's just too tricky to manage this. Ubuntu / RedHat preseeds and
kickstarts can create the user and add it to groups, but only when
we control the initial boot environment (ie not on Linode, Digital
Ocean, etc), so let's just say we assume this user exists and can
get root with sudo by the some we are running ansible on it.

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".
