util: enable golang profiling

Browse Source 
Add support for golang profiling.
Standard tools like go tool pprof and curl
work. example:
$ go tool pprof http://localhost:8080/debug/pprof/profile
$ go tool pprof http://localhost:8080/debug/pprof/heap
$ curl http://localhost:8080/debug/pprof/heap?debug=1

https://golang.org/pkg/net/http/pprof/ contains
more details about the pprof interface.

Fixes: #1699
