Bug 1279819

Description of problem:

Instruction wizard "Content Host Registration" leaves out steps to attach a subscription and enable repos.

Step 4 says install katello-agent which you 
cannot do as you have no repos at that point.

If you chose to use an activation key:
Step 3 assumes that your activation key provides access
to a subscription & content view (or has auto-attach set to 'True').
Otherwise, there step 4 would not work.

If you chose not to use an activation key:
You still need to attach a subscription and enable some repos.

Version-Release number of selected component (if applicable):
[root@rhel7-1-sat6 ~]# rpm -q katello
katello-2.2.0.16-1.el7sat.noarch
[root@rhel7-1-sat6 ~]# rpm -q foreman
foreman-1.7.2.43-1.el7sat.noarch

Steps to Reproduce:
1. Click Hosts → Content Hosts and then click Register Content Host.

subscription-manager list --available --all
subscription-manager attach --pool=<pool_ID>
