Usecase UI Project

In previous releases of UUI, in the docker image of the UUI server, there are also have Postgres database services. This a relally bad practice, a docker container have 2 components can lead to security issus.

And in kohn release, we use common postgresql chart instead of embedding database server.  We use a separate Postgres docker container, and moodify the existing code of UUI server to point to the new database.

And also modify the deployment script of the UUI server to support the separate Postgres database.
