Update Iptables reverse proxy documentation to include support for unix domain sockets

[kmartens27]

Describe your use-case which is not covered by existing documentation.

As a result of merging this packaging pull request, Jenkins now supports Unix domain sockets.

The various reverse proxy configuration pages need to be updated accordingly to include this new information. This ticket is for the Iptables reverse proxy specifically, as other configurations will have their own tickets.

Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.

Hi @kmartens27,

I understand that I have to update this document: https://www.jenkins.io/doc/book/system-administration/reverse-proxy-configuration-with-jenkins/reverse-proxy-configuration-iptables/

What shall I write about Unix domain sockets support? A single line that tells Unix domain sockets support is available?

And in which part of the document?

Hi @Jagrutiti thanks for taking a look at this!

Ideally there would be content added to the Iptables reverse proxy documentation that adds this Unix Domain Sockets support. It would need to include example code showing how to configure this, as well as some information about what that means for Iptables specifically.

If you have a good level of knowledge regarding Iptables reverse proxy configuration and can create the example code/add documentation stating what the support means, that should be enough information.

I don't personally have that level of knowledge when it comes to reverse proxies, so it may need a bit more information than what I've suggested, but not a lot. However, that could be discussed in a potential PR.

As far as I can tell, there is no way to use iptables with unix domain socket
