Currently, startup failure of DHT and/or averager (e.g. when
initial_peers
are unreachable) leads to a deadlock in the parent process. The exception message is printed to stdout but the parent process does not stop, and this is not nice for tests and end users.This PR makes startup errors to be propagated to the parent process.
