Allow exposing pprof endpoint

[avorima]

Description

Expose pprof endpoint from controller-runtime when enableProfiling=true helm value is set. Value is disabled by default.

How can this be tested?

Deploy and check out profiles.

make deploy
kubectl port-forward -n dynatrace deployment/dynatrace-operator 6060:6060
go tool pprof http://localhost:6060/debug/pprof/profile   # 30-second CPU profile
go tool pprof http://localhost:6060/debug/pprof/heap      # heap profile
go tool pprof http://localhost:6060/debug/pprof/block     # goroutine blocking profile
