Erik Grinaker 2f4c1f60c7 statesync: broadcast snapshot request to all peers on startup (#5320) 
On startup, the peer-to-peer stack may have peers connected before the state sync process begins, causing these to not trigger `AddPeer` events and thus not be used for snapshot discovery. Broadcasting a snapshot request to these explicitly makes sure we discover snapshots from existing peers as well.
