Cancels the subscription.
If the subscription is in dunning, it'll be taken out of dunning.
If the shop has an actions set to trigger when a subscription is cancelled, they'll be triggered (example: email notifications).
NOTE: If the request to cancel the subscription in Shopify fails, the subscription will still be cancelled in the Awtomic system to avoid future billing attempts.
