Section Number and Name: section 7.1 registering an existing host

Describe the issue: in section 7.1, step 3 the user is informed to run the following to register an existing system.  

 # subscription-manager register --org $ORG --activationkey ak-Reg_To_Dev_EL7 --environment Default_Organization/DEV


Suggestions for improvement: 

This command will not work for the following reasons:

- --environment _cant_ be used with activation keys. (There is no need to. Environment is implicitly part of what activation keys set)
- in section 6.6, we have the user create an activation key for the purpose of registering a system (which differs in naming from the above command)
- --environment requires lifecycle_environment/content_view and the above command uses organization/lifecycle_environment. 

Additional information: 

simply removing the --environment option from the command is sufficient to achieve the desired result (registering an existing system).
