Standardize usage of labels, milestones and automations

[ChristophWurst]

Our apps all have some special handling for their labels, milestones and some automations.

Examples

• Calendar has enhancement-proposed and enhancement-approved labels. No other app has that
• Mail has a bot that closes stale tickets after some time. No other app has that
• Contacts branches and milestones are chaos.

Todo

• [x] Unify label usage
  • https://docs.nextcloud.com/server/stable/developer_manual/prologue/development_process.html#the-labels
  • https://docs.nextcloud.com/server/latest/developer_manual/getting_started/codingguidelines.html#labels
  • Use common descriptions from documentation
  • Unify common labels colors
• [x] Unify milestone usage (needs documentation) https://github.com/nextcloud/groupware/pull/19
• [ ] Unify automations (possibly needs documentation) https://github.com/nextcloud/groupware/pull/21
  • Calendar uses https://github.com/nextcloud/calendar/blob/main/.github/no-response.yml (no response bot)
  • Contacts uses https://github.com/nextcloud/contacts/blob/main/.github/stale.yml (stale bot)
  • Mail uses https://github.com/nextcloud/mail/blob/main/.github/stale.yml (stale bot)
  • https://github.com/actions/stale looks promising
• [x] Add CalDAV and CardDAV labels in server

Note for the automation: close tickets in two steps. First announce that we will close if there is no more activity, then we close.

These are our organization defaults for new repos. They look clean.

Just in case: there is also https://github.com/nextcloud/github_helper/tree/master/label-updater around which could be used to unify those on existing repositories as well
