Description

About seven months ago, code was added that logged warnings if worker hooks were added in a config file, but workers were not used (workers = 0). The code only checks for workers being set in the config file. So, if one uses -w2 as a cli argument, the warnings are incorrectly shown.

Running the additional test in master fails, with the following:

  1) Failure:
TestIntegrationCluster#test_worker_hook_warning_cli [/mnt/c/Greg/GitHub/puma/test/test_integration_cluster.rb:518]:
Warning below should not be shown!
Warning: You specified code to run in a `on_worker_boot` block, but Puma is not configured to run in cluster mode (worker count > 0 ), so your `on_worker_boot` block did not run

Found while working with the new test framework server files...
