GitLab

We should re-implement, in a GitLab-compatible way, the issue triaging tools we had on Redmine to identify:

• "Stalled work-in-progress"
• "Reviews waiting for a long time"

This will require a dedicated API key:

• Decide what level of authorization the user must have → "Reporter" on all projects, in order to be able to see confidential issues
• Create a GitLab user for ticket triaging
• Generate an API key
• Add the API key to the place where it'll be used (ticket triager machine, puppet-tails_secrets_jenkins, puppet-lizard-hiera-node, or what not, depending on where the issue reminder code will run

For more detailed information, pointers, and implementation ideas, see:

• https://salsa.debian.org/tails-team/gitlab-migration/-/issues/54
• https://salsa.debian.org/tails-team/gitlab-migration/-/issues/75

Remaining problems after the first trial run, that created #17853 and #17854:

• Summary issues that this creates should be assigned to the ticket gardener → should be the case once tails/gitlab-config!7 is deployed
• Summary issues that this creates should get appropriate labels (needs tails/gitlab-config!7):
  • at least To Do and T:Communicate
  • perhaps a new, dedicated label, shared by all such automatically created triaging issues?

Finally, once this is all merged & deployed, final cleanup steps:

• Remove from our Puppet code base all traces of the previous, Redmine-based implementation
