Setup debugger

[alcalawil]

To test:

1. checkout task/wil/setup-debugger in infra repo
2. Create a .vscode/launch.json file. You can use the below example (replace <ABSOLUTE_PATH> with your real absolute path to the project folder

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Delve into Docker",
            "type": "go",
            "request": "attach",
            "mode": "remote",
            "substitutePath": [
                {
                    "from": "<ABSOLUTE_PATH>/string-api",
                    "to": "/string_api",
                },
            ],
            "port": 2346,
            "host": "127.0.0.1",
            "showLog": true,
            "apiVersion": 2,
            "trace": "verbose"
        }
    ]
}

4. in the infra repo run docker compose up --build
5. docker ps to make sure containers are healthy. In the ports section you should see that new ports (2345 and 2346) are exposed. These ports are used by vscode to send/receive events to/from the Delve debugger.

5. In vscode go the debugger tab
   

6. click on Delve into Docker, now you should see the debug buttons (pause, restart, step over, step in, stop), the debug console in debug bar, and you can set breakpoints.

7. Put some breakpoints in the code, go to Postman and send a request. If the code is reachable it should stop on the breakpoint.
