Steps

1. compile the binary with source path and symbols avaialbe
2. copy the binary into this directory
3. edit your workload and replace command+args with sleep infinity, remove readinessProbe/liveneesProbe
4. review path substitution config, change if needed
5. execute script run-kuma-dp.sh
6. setup port-forward: dlv-port-forward.sh
7. attach on JetBrains GoLand
