1) Adds a DB migration for all services to toggle on push, issue, and merge events.
2) Upon an issue or merge request event, fire service hooks.
3) Slack service supports custom messages for each of these events. Other services
not supported at the moment.
4) Label merge request hooks with their corresponding actions.
Make the Markdown parser recognize "[x]" or "[ ]" at the beginning of a
list item and turn it into a checkbox input. Users who can modify the
issue or MR can toggle the checkboxes directly or edit the Markdown to
manage the tasks. Task status is also displayed in the MR and issue
lists.
When a webhook for issues is triggered, it should also return the
resource URL, and the action that was performed (ie: Was it reopened,
updated, opened or closed)
The goal of suych refactoring is to get rid of observers.
Its much easier to test and code when object creation and all other
related actions done in one class instead of splited across observers,
callbacks etc.
