Automate posting of release notes to Slack

[coreycarvalho]

User Story - Business Need

Currently, at the end of every release, a developer manually copies and pastes the release notes into Slack. In order to fully automate the CI/CD pipeline, we need to remove the manual step of copy/pasting the release notes into Slack.

• [ ] Ticket is understood, and QA has been contacted (if the ticket has a QA label).

User Story(ies)

As a VA Notify developer I want automatic release note posting to Slack So that I don't have to copy and paste them manually.

Additional Info and Resources

Acceptance Criteria

• [ ] When the CI/CD pipeline finishes, and a new version is released to production, release notes are automatically sent to Slack
  • [ ] #va-notifications-va-gov-program (Oddball)
  • [ ] #va-notify-public (Office of CTO @ VA)

QA Considerations

• work with Dev on any formatting/language needs for the posts that get made to Slack.

Potential Dependencies

If we want to post to the Oddball workspace, we will need an API token or a Slackbot set up to be able to do that. Will have to reach out to somebody on the Oddball side for that.

@cris-oddball Can you track down the anomaly detection ticket and set as a blocker to this ticket? Thank you!

[cris-oddball]

The anomaly ticket is now listed as a blocker.

@coreycarvalho we also need to understand when the release notes would be posted to slack? via another pause for approval step in the pipeline or automatically based on the results of anomaly detection? In other words, we only want to post release note when we are satisfied that the release was a success.
