Add tutorial for running Kuma on universal using Docker and our published images

[jijiechen]

Description

In our current version of Universal quickstart guide, we are teaching people run kuma-dp and kuma-cp services using the binaries directly. From a VM perspective, people also would like to run 3rd party software using the Docker tool chain, etc.

The approach we introduced in our current guide has a few drawbacks:

• the user needs to run multiple kuma-dp instances on the same host. This is not a typical nor recommeded way of running Kuma
• Running multiple kuma-dp instances on a single host bings some issues:
  • Port conflicts, reported by multiple users, for example: https://github.com/kumahq/kuma-website/issues/1997
  • Transparent proxy can't be enabled hence Mesh DNS support can't be used by the application
• Envoy depends on a higher version of glibc, this can cause troubles for some users who are using distrios shipping with older versions of glibc

So it's benifitial to include a tutorial helping people build application images combined with Kuma images with their own application images, and introduce how the mesh is run in this way.
