Multi-database support in UI

Feature Request
#1

In project settings, server target, you can only specify the details of one database server - it’s not ready for multiple databases

In my case, I want to use a separate secondary database to put less-critical, more resource-heavy stuff (hint hint: time-series database with lots of data)

This feature request means it would support adding multiple databases to a local Docker environment, as well as deployment

#2

Well in docker you usually have a single database and maybe also Redis server, Running more database servers on the same docker server will just totally overload your server.

But you can also add as many additional external database connections as you want!

Just add them in the Database Manager and they will be also added as Server Connect Global Database Connections and you can use them as you wish.
