[consensus] KUDU-2302: don't crash if new leader can't resolve peer

When a tablet replica is elected leader, it constructs Peer objects for
each replica in the Raft config for the sake of sending RPCs to each.
If, during this construction, any remote peer cannot be reached for
whatever reason, this would result in a crash.

Rather than crashing, this patch allows us to start Peers without a
proxy, and retries constructing the proxy the next time a proxy is
required.
