Enable SSL when requested

[zachfi]

Without this change, a true value on nignx::resource::server::ssl does not
result in the 'ssl on' directive necessary to enable SSL in some cases, like
IPv6. Here we include a fix to adhere to the user request to enable SSL for the
given nginx server.

I think maybe this is just me not knowing the state of nginx.

This PR includes the ssl on in my config, but after upgrading 1.14.2_13,2 -> 1.16.0,2 I now see this warning in my nginx -t.

nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in /usr/local/etc/nginx/sites-enabled/zleslie.info.conf:20

I guess its still a step in the right direction, but I need to read the nginx docs for a different PR to fix the listen lines, but probably someone will get to it before me.

Hi @xaque208, thanks for the PR. Can you please rebase this PR and also check #1330 ? That might address your issue here as well.

I will close this pull request, because this issue has been solved by #1330.
