Expand the webhooks to support availability block updates
Currently, an integration partner that uses group block data (such as Revenue Management Systems, Event Management Systems, Central Reservation Systems, etc.) needs to poll "availabilityBlocks/getAll" at a scheduled interval and are not able to sync availability blocks in real time.
In order such integration partners to follow the best practices (https://mews-systems.gitbook.io/connector-api/guidelines/best-practices), they need the general webhooks expanded with new availability block-based events notifying the partners when:
- an availability block has been created
- an availability block has been updated
- an availability block has been deleted
- an availability block's service availability has changed
