Turtles Inventory

[Rotfuks]

Motivation

Team turtles has the ownership responsibility for a lot of components and apps. But we never really looked in detail into those components to define what exactly these components are, do and need. So this epic should document a clear inventory for all turtles owned apps.

### Stories
- [ ] define what a expected state for an app is (documentation, tests, monitoring, stability, etc)
- [ ] define the list of components and apps we want to take a look at
- [ ] investigate the state of the app list
- [ ] document the open points, risks and issues with apps from the app list
- [ ] https://github.com/giantswarm/roadmap/issues/2540

Outcome

• After doing the inventory we have a clear overview over all the apps we own in turtles, this means
  • we collected and organised all existing internal and external documentation
  • we derived follow up epics for any work necessary to fulfill our quality requirements for apps
  • we extended the documentation with all technical debt and issues that we have and accept with the app
