Ville Skyttä 25f9097e22 nginx_proxy: Update run.sh info messages, make HSTS configurable and optional (#264)
* nginx_proxy: Update run.sh info messages

In particular, note that generating dhparams will take some time.

* nginx_proxy: Bump version to 1.1

* nginx_proxy: Make HSTS configurable and optional

Unconditional HSTS breaks unencrypted connections to non-standard HTTP
ports on the same hostname. These ports be e.g. mapped outside of
hassio/nginx, and this can not be always circumvented by proxying them
beind nginx, because not all services behave properly behind a reverse
proxy.

Additionally, the unconditional HSTS includeSubDomains setting
hardcodes assumptions about subdomains that hassio does not
necessarily deal with at all.

* fix style
