anastasia 3b61f364f7 Stop WAL streaming threads, when compute node is shut down. ...

WAL stream uses the 2 connections:
1. Compute node (walproposer) -> Safekeeper (ReceiveWalConn module)

When compute node is shut down, safekeeper needs to stop the respective receiving thread.
Prior to this PR it didn't work because PostgresBackend haven't handled disconnection properly.

2. Safekeeper (ReplicationConn module) -> pageserver (walreceiver thread)

When incoming WAL stream is gone, safekeeper can stop streaming WAL and cancel connection as soon as replica is caught up.
Note that the WAL can be streamed to multiple replicas simultaneously, only disconnect ones that are caught up to the last_recieved_lsn.
