Description of problem:
The API docs (https://fqdn/apidoc/v2/hosts_bulk_actions.html) states that the routes are prefixed with 'katello' e.g.:
 
PUT /katello/api/hosts/bulk/install_content 

when the actual routes are without the 'katello' prefix:

<pre>
# foreman-rake routes|grep install_content
                                   bulk_install_content_api_hosts PUT    /api(/:api_version)/hosts/bulk/install_content(.:format)                                                                                               katello/api/v2/hosts_bulk_actions#install_content {:api_version=>/v2/}
</pre>

Version-Release number of selected component (if applicable):
# rpm -qa|grep katello
katello-3.2.0-2.rc1.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1. See the routes in https://fqdn/apidoc/v2/hosts_bulk_actions.html
2. foreman-rake routes|grep install_content
3. Check if they match

Actual results:
No

Expected results:
Yes 

Additional info:
(I'd expect no katello prefix in the apidoc)
