What can be configured in config.ini

Hi,

in https://github.com/Icinga/icingaweb2/tree/master/doc you can find some documentation about how to configure Icingaweb2 but the documentation is not complete.

For example, here is the documentation for config.ini: https://github.com/Icinga/icingaweb2/blob/master/doc/03-Configuration.md#configuration-general

But I know that there is this configuration which can also put there:

[cookie]
path = "/"

I am really curious what other configuration values can be placed here and maybe in other files too. Is there a complete list of all the sections and options somewhere?

And are there any more environment variables which can be set on apache/httpd/nginx level?

I would be nice to see a full documentation of all the possible configuration values.

Thanks.
