Jenkins Plugin Dependency Installation Inefficient Recursion

[Hookyhook]

Summary

Using with_dependencies flag when using jenkins_plugin leads to ultra long task execution.

Potential Reason:

After a first quick investigation I noticed that in this plugins recent changes introduced a new recursion logic that seems very inefficient and problematic. Requests are never cached but called multiple times etc.

CC @YoussefKhalidAli, since this might have been introduced in #10346.

I have the same issue. Before this change, it took around five minutes, but now I cancelled the run after 15 hours this time.

Can I help somehow?

Currently for a workaround I set the 11.1.2 communit.general collections in the requirements.yml and install ansible-core instead of ansible in my virtual environment.

collections:
  - name: community.general
    version: 11.1.2

I guess adding code that prevents the recursive algorithm to query the same thing multiple times would help. Maybe also just passing with_dependencies=false (not sure what other implications this has though).

PRs to improve the plugin are always welcome.
