This commit updates geth to 1.8.17 and adds a possibility to enable metrics during compilation time. The cascade of issues forced us to upgrade geth to 1.8.17 in order to allow enabling metrics during compilation time. 1.8.17 introduced `NodeID` refactoring and `enode` package which affected our peers pool and integration with Discovery V5.

ping-pong
ping-pong.go implements a simulation network which contains nodes running a
simple "ping-pong" protocol where nodes send a ping message to all their
connected peers every 10s and receive pong messages in return.
To run the simulation, run go run ping-pong.go in one terminal to start the
simulation API and ./ping-pong.sh in another to start and connect the nodes:
$ go run ping-pong.go
INFO [08-15|13:53:49] using sim adapter
INFO [08-15|13:53:49] starting simulation server on 0.0.0.0:8888...
$ ./ping-pong.sh
---> 13:58:12 creating 10 nodes

---> 13:58:13 connecting node01 to all other nodes

Use the --adapter flag to choose the adapter type:
$ go run ping-pong.go --adapter exec
INFO [08-15|14:01:14] using exec adapter tmpdir=/var/folders/k6/wpsgfg4n23ddbc6f5cnw5qg00000gn/T/p2p-example992833779
