recovery bug in sender:
- recovery is invalid in sender.
- some tsfiles maybe re-sender to receiver.
- some tsfiles maybe be deleted on receiver twice.
- now make the recovery valid in sender
reconnection bug in sender and receiver:
- reconnection is invalid both in sender and receiver
- maybe cause the receiver delete some tsfile which should not be deleted, because the log in receiver is wrong when time partition and vg is enable.
- maybe cause the sender can not connect to the receiver after the reconnection, because some info in receiver is missing after reconnection.
- now the reconnect can be set correctly.
remove some debug info in receiver
