more secure
Added SSL caching to speed up SSL requests
Add server_tokens to the global config so this can be turned on|off
between dev and prod
Add proxy_set_header to vhost as different vhosts may require different
headers and the global setting is not ideal
Minor space formatting so that the generated files are fractionally
more readable
Defaults are set inside params, nginx class will set default and send it from local var to nginx::config,
so even when there is no need for set default values on nginx::config, in case someone already using
this module it's for some reason calling directly nginx::config, to avoid breaking anything defaults are
set inside nginx::config too.
