Description of problem:

There are some functionality differences observed in the Rest API of Satellite 6 and subscription-manager in terms of Simple Content Access mode.

---------------------------------------------------------------


Version-Release number of selected component (if applicable):

Satellite 6.9 and above

How reproducible:

Always


Steps to Reproduce:

Please check the reproducer.txt file attached on the Bugzilla. 


Actual results:

Using subscription-manager we can attach subscription to the host even while SCA is enabled but Satellite API fails to do so.

Satellite API also fails to attach subscriptions to any activation key.

But in both cases, Satellite API will be able to remove subscription i.e. from both HOst and Activation key.


Expected results:

A consistent behavior should be present for all subscription_management tools when it comes to SCA.

Either disable the subscription attachment feature completely for subscription-manager when SCA is enabled or re-enable the capability of satellite REST api to be able to attach the subscriptions on the hosts as well as activation keys.


Additional info:

We created a simple content access feature, to give some relaxation to the end-users i.e. even if they don't attach subscriptions to the hosts, they can use yum without worrying about overconsumption of the subscriptions or anything else but we never said, they are not allowed to attach any subscriptions to hosts. 

So we either need to make our point of view clear to the end-users if we expect to have no subscriptions attached to the systems at all or if we leave that choice to the end-users, then have the subscription_management tools behave in a consistent way.

There's no problem in having auto-attach disabled but manual attachment should work.
