Add warning about misconfiguration if faulty_peers = 0 and trusted peers count > 1

[rkharisov]

Precondition: MAX_FAULTY_PEERS set to 0 or not set at all (in this case default value will be 0). Trusted peers contains more than 1 peers

Expected behaviour: There is some warning about misconfiguration in logs

Current behaviour: No hints about misconfiguration

Description: MAX_FAULTY_PEERS=0 effectively means peer will work in standalone mode without other peers, while trusted_peers.json provide a list of other peers in network. If MAX_FAULTY_PEERS=0 and trusted peers count > 1 that most probably means misconfiguration
