feat(delayed job): allow to select the modules as part of the jobs name

[martinramirez7]

This PR allows to use modules as part of jobs names on delayed jobs metrics.

This is useful in apps with several namespaces where each defines the same set of jobs, all running in the same queue, which is our situation.

It ensures backwards compatibility.

Hey @SamSaffron, can you take a quick look of this please? It seems linter is failing on unchanged files

[SamSaffron]

any chance you can add a test to properly clarify new behavior ?

[martinramirez7]

Hey Sam, just added the new param to some tests. I don't really understand why the CI's tests are failing, any idea? locally works fine. I believe it has nothing to do with my changes. let me know if I'm wrong

@martinramirez7 the specs are failing in master also, something changed. But is should be fixed if you add require 'ostruct' to the /test/server/runner_test.rb file.

@SamSaffron I added a commit that fixes the CI problem with @blackjid suggestion. The problem is due json 2.7.2 doesn't load open struct library by default as it was on 2.7.1. you can see this PR for mor info
