Description of problem:
With the introduction of instance based subscription pools as well as core, ram, and socket based subscriptions, attaching a subscription from the CLI is frequently leaving the CLI consumer partially subscribed.  This is because a quantity of 1 is used by default when the CLI consumer does not explicitly specify a quantity.  Moreover, it is increasingly more complicated to know what quantity is needed.

The subscription-manager GUI quantity spinners already provide the user with a suggested quantity needed to achieve compliance.  It would be good to have the CLI list --available report also provide a suggested quantity.

Taking this one step farther, it would also be helpful for the candlepin server to automatically give a CLI consumer the quantity needed to achieve compliance when the --quantity option is not explicitly specified by the CLI consumer.  However, this functionality would be a candlepin RFE Bugzilla.
