[DISCUSSION] New events api and ui

[tusmester]

We want to display events related to the repository in admin ui. We need to decide which events do we need to show and there are some other architectural questions.

• display events only for the current repository
• events should be accessible from anywhere, not just locally where they happened (backend log, not frontend)
• which events do we want to show?
  • content CRUD
  • security? (permission change, log in)
  • other server-side events, not related to contents?
  • Do we want to integrate client-side errors? (for example store "server unavailable" errors locally and send them to the backend later?)
• filtering
• security: who can see which events? Eg, events related to a content that I do not have permissions for.
