Connect to already running instance of DynamoDB Local

The Toolkit allows users to start an instance of DynamoDB Local and connect to it, however the toolkit owns the lifecycle of DynamoDB Local. It should be possible for users to stand up an instance of DynamoDB Local on their own (and manage its lifecycle), and connect the toolkit to an already running instance of DynamoDB Local.

Original issue text:

Hello.

I installed and run DynamoDB Local in Docker, with port 8000.

But I couldn't connect to DynamoDB Local with this toolkit. This toolkit force me turn on new DynamoDB java process.

Could you let me know how to just connect to running DynamoDB Instance?

Start by locating the toolkit code that starts and manages DynamoDB Local, then inspect how a connection to the local port is configured. Done means the toolkit can connect to a user-managed DynamoDB Local instance, including one running in Docker on port 8000, without starting its own Java process.
