This change allows users to specify a custom nginx.conf.sigil that can expose non-web process types to the outside world in addition to the web process type.
Closes#3258
This enables the HSTS header by default when an SSL certificate is in use. HSTS options can also be managed via the nginx:set command, which also exposes the ability to disable HSTS for your application.
- expose an nginx:validate command that can be used to show validation information
- properly reference the invalid nginx config, rather than tell the user that another app's nginx config is invalid when deploying their own app
- allow a user to cleanup bad nginx config files out of band when they are blocking a deploy _without_ requiring knowing where that nginx config is
Note that this may have issues with generated nginx.conf files that depend on other apps or other parts of the nginx config. For now, this is acceptable, though it is something that needs to be field tested.
Closes#3162
These examples do not include _all_ of the contents of the original template. Rather than having to keep them up to date and confuse users when we don't, lets just remove them. The section above contains a link to the current `nginx.conf.sigil` and should be referenced by our users instead.
Closes#3068
