As an API user, I want to delete subscriptions from my allocation.
Interfacing with the Portal should not require the user to provide username/password. Instead, the certificate from the manifest may be used.
Interfacing with the Portal should work with or without a proxy located between it and the Satellite server.
The ability to delete subscriptions is controlled by the 'manage_subscription_allocations' permission.
API : Given a pool id and katello organization, user may delete a subscription from the allocation.
API : An appropriate error should be returned to the user in scenarios such as, invalid pool id, katello organization, manifest not imported, permissions denied...etc
The subscriptions are deleted from the allocation both on the Portal and Katello.
At this time, this will be accomplished by a task that updates the Portal and upon success initiates a 'refresh manifest' on Satellite.
After deletion, the subscription is included in the 'available subscriptions' list.
