Read recovered position from sst_received() after initialization

Browse Source 
In general the position where the storage recovers after a SST
cannot be known untile the recovery process is over. This in turn
means that the position cannot be known when the server_state
sst_received() method is called. Worked around the problem by
introducing get_position() method into server service which
can be used to get the position from stable storage after SST
has completed and the state has been recovered.
