/**
* A general purpose function for grabbing an array of subscriptions in form of post_id => WC_Subscription
*
* The $args parameter is based on the parameter of the same name used by the core WordPress @see get_posts() function.
* It can be used to choose which subscriptions should be returned by the function, how many subscriptions should be returned
* and in what order those subscriptions should be returned.
*
* @param array $args A set of name value pairs to determine the return value.
* 'subscriptions_per_page' The number of subscriptions to return. Set to -1 for unlimited. Default 10.
* 'offset' An optional number of subscription to displace or pass over. Default 0.
* 'orderby' The field which the subscriptions should be ordered by. Can be 'start_date', 'trial_end_date', 'end_date', 'status' or 'order_id'. Defaults to 'start_date'.
* 'order' The order of the values returned. Can be 'ASC' or 'DESC'. Defaults to 'DESC'
* 'customer_id' The user ID of a customer on the site.
* 'product_id' The post ID of a WC_Product_Subscription, WC_Product_Variable_Subscription or WC_Product_Subscription_Variation object
* 'order_id' The post ID of a shop_order post/WC_Order object which was used to create the subscription
* 'subscription_status' Any valid subscription status. Can be 'any', 'active', 'cancelled', 'suspended', 'expired', 'pending' or 'trash'. Defaults to 'any'.
* @return array Subscription details in post_id => WC_Subscription form.
* @since 2.0
