The aim of this patchset is to give a user ability to update Vshard 
version without restarting
a server, even in case some relatively noticeable changes happened in 
the Vshard.

Vshard will:
   * reuse old connections
   * outdate old user-visible objects (replica, replicaset) wich a 
specified delay
   * reuse route map (after #117)
   * reload background fibers
