"Property processName is not allowed." in launch.json

[hsandt]

• VSCode Version: 1.22.2
• OS Version: Windows 10

The config.json parser does not recgonize the new processName parameter, only the processId one. Therefore, if you put processName but not processId, you'll get 2 warnings in the issues list:

• Missing property "processId"
• Property processName is not allowed.

Steps to Reproduce:

1. Create a launch.json configuration with this:

{
"version": "0.2.0",
"configurations": [
{
"name": "(Windows) Attach",
"type": "cppvsdbg",
"request": "attach",
"processName": "my_program.exe"
}
]
}

2. Open the Issues panel or go to next error (F8) to see the 2 errors mentioned at the beginning.

Does this issue occur when all extensions are disabled?: Yes

If someone introduces a new attribute like "processName", the schema must be updated too.
File this issue against the "cppvsdbg" extension.
