To take care of instantiating a canonical job queue for use across
all of WooCommerce, and by 3rd party code.
Also use this new API for enqueuing webhooks instead of raw Action
Scheduler APIs.
To make it clearer in the database what the args refer to, e.g.
instead of storing the scheduled action's args as:
[1,123]
This patch changes it so that the args are stored as:
["webhook_id":1,"arg":123]
This has no impact on callbacks on the hooks, they are still passed
the args as normal.
This will make it possible in future to run queues specifically for
delivering webhooks, instead of deliering webhooks in the same queue
as other actions, like scheduled payments, emails or other actions
scheduled by other plugins. This can be used to provide better
control over webhook delivery, which allows for sending webhooks more
quickly than if they are only included in batches of other actions.
