Subcommands missing from help pages

[pedro-psb]

Summary

Some subcommands are not shown in the respective command help page.

Steps to reproduce

I've spotted two recently: pulp rpm content upload and most root pulp subcommands commands.

# doesn't show plugin commands, nor task, workers, show, debug, etc
pulp --help

# doesn't show the 'upload' subcommand in neither form
pulp rpm content
pulp rpm content --help

# edit: specifying the --type shows it correctly
pulp rpm content -t package --help

Expected behavior

Expected that all available subcommands are shown.

Pulp and pulp-cli version info
