Feature request: start to debug c++ directly from command line.

Type: Debugger
Input information below

This a feature request. Currently, to debug the exe or attach a process, I've to setup launch.json, which is very tedious if you just want to do some quick very verification.

Request: start to debug directly from command line, eg

code -e cpp -d ./a.out arg1 arg2, argN: to debug a.out with arg1 and arg2.... argN
code -e cpp -p 12345: attach process 12345.

"-e cpp" means "pass the following parameters to vscode-cpptools extension."

As a comparison:

In visual studio, you can devenv.exe /debugexe a.exe

Eclipse has a plugin: https://github.com/eclipse-cdt/cdt/blob/master/debug/org.eclipse.cdt.debug.application/scripts/cdtdebug.sh, which allow you to start debug from command line.

Emacs (which is close to VScode since both VScode and emacs are editors while VS/Eclipse are IDE, you can pass some parameters https://stackoverflow.com/questions/5997309/start-emacs-gdb-from-command-line to start debugging directly.

The request proposes code -e cpp -d ... and code -e cpp -p ... as command-line entry points for the cpptools extension. Start by locating the extension’s command-line and debugger entry points, then verify that done means launching an executable with arguments or attaching to the specified process without launch.json.
