[RFC PATCH 09/12] box: connect to remote peers before starting local recovery

[Vladimir Davydov]

box_sync_replication() can now be called before recovery, right after
box_listen(). This is a step toward detecting if the instance fell too
much behind its peers in the cluster and so needs to be rebootstrapped.

Needed for #461
