Supporting Memberships

In addition to the changes needed to support Subscriptions with Submarine, Memberships require a metafield to be added.

In the Shopify Admin, Membership products are identified by the presence of a _membership_duration variant metafield, i.e. 3_months. Note that this frequency must match the subscription frequency set by the source Shopify order (as per regular subscriptions) or a membership subscription will not be created.
