[CI] Automatically create issues when pipeline on `master` fails

Related to gitlab-org/distribution/team-tasks#818 (closed)

Summary

When CI fails on the default branch (currently master), it would be nice to have an issue automatically created with relevant information.

As a first iteration, we can implement https://gitlab.com/mnielsen/issue-bot.

Acceptance criteria

• CI runs https://gitlab.com/mnielsen/issue-bot upon failure on master
• Issue board exists that uses issue-bot's scoped labels for easy tracking and triage
