Enhance: activating profiling at runtime

[iltoga]

Description

Enable profiling for nodes at runtime as explained here: https://blog.golang.org/pprof

This way we can run deployments were all nodes do profiling profiling while running and export a .prof file that can be later inspected to have better insights when debugging performance issues, such as high cpu loads and memory leaks

Breakdown

• Add cpu and memory profiling at runtime via flag "cpuprofile"

Expected behavior

When running the go binary with -cpuprofile flag, a .prof file containing profiling informations will be generated.
