chore(allsrv): add pprof routes

One last bit of important data we're missing is our profiling. This can be
applied at any time in the development. Its added here last because there is
already a lot to cover before thi. However, with these endpoints, you can
create profiles that will breakdown difference performance characteristics
of your system. One of the beautiful things here is you can grab the
profiles ad-hoc or create a recurring drop to grab profiles at different
intervals. Regardless when or how you do it, it all goes through the
HTTP API :chef_kiss:.
