Plugin API for extending template helpers does not work

Description
We added extend_template_helpers API methods but it does not work, methods added via this extension are not available in Foreman::Renderer. Rendering is not possible:
Create a plugin, add new method, try to use it in a template in both safemode and non-safemode. Result:
There was an error rendering the Discovery Red Hat kexec template: undefined local variable or method `discovery_kexec_kernel' for #<#<Class:0x0055f4717ade40>:0x0055f471772c28> Did you mean? discovery_rule_url

Side note: I observed that the extension mechanism is called every request, so every request we are iterating through plugins and re-including and re-extending all methods.

Lukas, could you please add a reproducer? It seems to work fine for foreman_chef and I don't see how it would be called multiple times if you put this into the plugin initializer.
