Please document the default values of the options

[ChristianCiach]

I am trying to migrate from mod_auth_openidc, but I find the documentation inside the conf-file very confusing and lackluster.

For example, I am trying to find out which of the options like ssl_verify and verify.exp I actually need to specify. Unfortunately, their default values don't seem to be documented.

yes, documentation is a work in progress and the sample config file is the only source right now

I'll assume that the link from the README to a wiki that doesn't seem to be there also isn't an unknown issue, then!

(sorry for hijacking this issue report if it is)
