Subject: nginx: add common role for nginx

esmil:
- disable access log and log errors to syslog (journal really)
  use journalctl -u nginx to see the errors
- hoist some configuration values into ansible variables
- add tags and use a handler to reload nginx on configuration changes
- make nginx do its DNS queries against our local resolved
  this enables nginx to use DNSSEC and DoT
- don't start nginx before the network is up. if it can't do
  dns lookups ssl_stapling will be ignored
