[self-hosted] Release Gitpod Self-Hosted 0.9.0

[geropl]

ToDo:

• update to latest Gitpod as from gitpod.io (as usual)
• docs:
  • reflect our matrix of supported platforms more prominently
  • update remove OAuth config to focus on dynamic setup: the dynamic part is already documented as part of the "regular" docs
• build missing UI:
  • reinstate terms page: [self-hosted] UI: Re-instantiate first-steps/initial-setup page #3920
  • handle SETUP_REQUIRED: [self-hosted] UI: Re-instantiate first-steps/initial-setup page #3920
    • initial Git Provider (on demand)
    • first user to be admin
      - [ ] handle EE_LICENSE_REQUIRED [dashboard] Handle EE_LICENSE_REQUIRED #3918
      - [ ] Upload License page with a website link to buy the license from
• remove deprecated installer images
  - [ ] [self-hosted] Make our Self-Hosted terraform scripts infrastructure only #3912: adjust (and fix) terraform scripts so they are not geared towards installers anymore (and fix Wrong value of DB_ENCRYPTION_KEYS #3766 along the way)

@dimazaur

Could you share your roadmap?

You mean our general, Gitpod roadmap? here it is

Are you going to fix Self-Hosted in 0.8.0 or in 0.9.0 version?

The 0.9.0 version.

And what is the schedule?

We originally planned end of this week, but looking through the ToDos (cmp. above) I guess it might as well become next week. Upper bound is end of April's cycle, though. 🙃

Excluded #3912 and marked as stretch goal for this release due to time constraints 😢

Move EE_LICENSE_REQUIRED related work to May due to time constraints.
