* feat: obtain external address for rendezvous
If the ext ip returned by geth is 127.0.0.1, it will attempt to obtain the external IP address via rendezvous and use that to register the ens record later
* fix: failing test
* fix: code review, and adding external ip address to logs
It was going to be used as proxy from discv5 to rendezvous for les nodes.
We are not using it at the moment, and not clear when we will be using it
and if we are going to use it all.
Additionally it has some memory leaks that need to be fixed, so it is better
to remove it for now and restore once/if we will need it again.
Libp2p keeps stream open if EOF wasn't seen and we called Close method.
The most important change is that reader now uses FullClose util, that will
wait for EOF character before closing the stream.
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.

Integrate rendezvous into status node
Add a test with failover using rendezvous
Use multiple servers in client
