Title: Use subset of configurable attributes in configurable products

Allows for a configurable product to be configurable on a subset of the
attributes that can be used. For example if an attribute set has three
attributes that can be used to configure a configurable product, but the
admin only wants to use two, they can be set in the productData array when
calling product.create.

array (
'configurable_attributes' =>
array (
0 => 'size',
1 => 'color',
),
)
