WEBHOOK Support for Issue Linking change
Problem to solve
As a GitLab administrator I want a WEBHOOK to fire when an issue is linked to another issue so I can automate a process to take action when issues are blocking each other.
See Ticket 158379
Intended users
User experience goal
When an issue is linked to another issue, a WEBHOOK should seamlessly be fired to notify the listening service.
Proposal
Currently a WEBHOOK can be configured to be fired for Issue updates. This WEBHOOK should be fired when the issue is updated with a link and the WEBHOOK should detail the links in the payload. The detail should included whether the issue relates to, is blocked by or blocks the issue it is being linked to.
