Description of problem: There is a subcommand in host_collection.rb named ContentBaseCommand with three actions, but there is no way to access them in hammer.
Version-Release number of selected component (if applicable):
6.2, 6.1, devel
Steps to Reproduce:
1. Run each hammer command below
hammer host-collection content-base install
hammer host-collection content-base update
hammer host-collection content-base remove
Error: No such sub-command 'content-base'
See: 'hammer host-collection --help'
I believe this hammer subcommand should be calling the hosts_bulk_actions_controller in Katello's API.
