We plan to use gossip data to educate Raft RPC about IP addresses of raft peers. Add raft server ids to application state, so that when we get a notification about a gossip peer we can identify which raft server id this notification is for, specifically, we can find what IP address stands for this server id, and, whenever the IP address changes, we can update Raft address map with the new address. On the same token, at boot time, we now have to start Gossip before Raft, since Raft won't be able to send any messages without gossip data about IP addresses.
