Add a new event type for subscriptions migrated to a bundle (#5)

* Add a new event type from subscriptions migrated to a bundle
* Bump API version to 0.1.0 as now we have a new field and a new event type
* Bump version to 1.1.0 instead of 0.1.0
* Change subscription migrated event name and move the declaration underneath subscriptions events
* Add subscription migrated as a valid type
