Node Subprocess Attach Port Selector

Select a node process before debug.

'launch.json' definition example:

{
    "type": "node",
    "request": "attach",
    "name": "Attach to subprocess",
    "port": "${command:freshx.node-subprocess-attach-port-selector}",
    "debug_ports": "${workspaceFolder}/debug_ports.json"
}

Needs a debug_ports file with scheme:

{
  "name": port,
}

Run nodeJs commands from main process with:

node --inspect $port $nodeJsFile
