autobind by pools
cleanup and let the db filter pools by ID
Fix tests
Expand activation key capabilities

Can specify group of pools and/or list of product ids to carry out a contained autobind as part of the registration with key process.
Also adds the ability to do a straight autobind.
The normal bind API also allows this operation.
Moved activation key spec tests out to separate file as consumer_resource spec is getting long.
Activation keys will now be run serially. Previously they were run with the pool application across all keys before the
overrides, SLA, and release were set each from across all keys.
Moved activation key bind logic to separate class to facilitate testing isolation
Move new activation key tests from spec to unit
Additional key behavior

A key with pools in the classic method will allow registration as long as one bind works.
A set of keys will allow registraton as long as one key works.
A lone key will block registration if the key is not available for the org or the service level
 specified is not found.
Simplify unit test scale
Better use of bind utility and product id instead of product
Autobind flag is now Boolean object
