test-daemon.rb
bundler
observer with logging
logger observer
logger for client
reuse logger from client in observer
loggable
use loggable in client.rb
use logger in cluster
that looks messy… but works somehow
logging for observers
move index in observer instance variable, so re-running possible
status for observers
logger from loggable
heartbeat now also responsible for observers refreshing, sometimes they die, even if the etcd cluster was ok…
remove comment
logging down to warn
moved a bit of logic to heartbeat class
a trick to detach from child process
split up the client class into 3 parts for readability
