Before redis#13732, replicas were brought online immediately after master wrote the last bytes of the RDB file to the socket. This behavior remains unchanged if rdbchannel replication is not used. However, with rdbchannel replication, the replica is brought online after receiving the first ack which is sent by replica after rdb is loaded. To align the behavior, reverting this change to put replica online once bgsave is done. Additonal changes: - INFO field `mem_total_replication_buffers` will also contain `server.repl_full_sync_buffer.mem_used` which shows accumulated replication stream during rdbchannel replication on replica side. - Deleted debug level logging from some replication tests. These tests generate thousands of keys and it may cause per key logging on some cases.
