Sybren A. Stüvel b511fad968 Manager: add profiler support
Add a `-pprof` CLI option to enable the profiler. It will expose profiler
info on the web interface at `/debug/pprof/`.

To have a nice view of this, including flame graphs, run:

```
go tool pprof -http localhost:8082 http://localhost:8080/debug/pprof/profile
```
