draft: feat: Install Observability using docker compose

[rboni-dk]

This PR also adds support to the DK_INSTALLER_ANALYTICS environment variable, which will disable sending events to MixPanel when set to anything different than Yes.

It's marked as draft because it only works with the yet top be released Observability images
