[Feature request] Send user settings of terminal choice during launch (e.g. user setting: terminal.external....)

I am trying to launch a debug session. Unfortunately, gnome-terminal fails to launch. However, xterm works fine. I am unable to get Visual studio code to use Xterm. Any Help Appreciated.

User Settings:

{
"workbench.colorTheme": "Quiet Light",
"editor.fontSize": 14,
"julia.executablePath": "/usr/local/bin/julia",
"files.associations": {
"*.jl": "julia"
},

"editor.fontFamily": "'DejaVu Sans Mono'",
"editor.fontWeight": "bold",
"editor.suggestFontSize": 11,
"clang.executable": "/srllc/tp/clang/v6.0.0/bin",
"clang.cxxflags": [
    "--std=c++11"
],
"terminal.external.linuxExec": "/bin/xterm"

}

"type": "cppdbg",

"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}/build",

},
"setupCommands": [

"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],

Start by reviewing the terminal.external.linuxExec setting in settings.json and the launch configuration in launch.json, then compare them with the reported debug launch output. Trace where the selected terminal is handled during a C/C++ debug launch. Done means the configured terminal choice is passed through and xterm launches instead of gnome-terminal.
