Allow/ensure single instance of support containers like DbGate

Existing integration

Most of the database ones at least

Overview

Many of the database extensions in this toolkit include helper methods to add DbGate in development to aid viewing database resources.

Postgres, SqlServer, Redis, etc. all have this option.

Adding that option to multiple - say Postgres and Redis - creates multiple instances of DbGate.

It would be cleaner and a better DX if it were smart enough to merge the configurations into a single instance.

I'm sure there are other examples of this too.

Usage example

var postgres = builder.AddPostgres("postgres")
    .WithDbGate()
var redis = builder.AddRedis("redis")
    .WithDbGate();

It should recognise that it has two things to link DbGate to and manage it as a single DbGate instance

Breaking change?

I'm not sure

None that I can think of

No, just wanted to propose this

It does merge into a single DbGate instance, here's a screenshot from running the example dbgate apphost:

Hmm... It created separate instances in my project. Let me test it in a clean project and I'll get back to you.
