Add VS Code launch examples

[jiparis]

This is a feature request to provide a basic launch.json VSCode file to easily run and debug Chainloop services, mainly the Control Pllane and the CAS.
Unfortunately, VS Code only allows 1 lauch.json file (no launch.local.json or similar), so this provided file would be generic and simple, but useful enough for the most basic use cases.
