Upload on GCS was broken with "InvalidArgument: Invalid argument. status code: 400"

PBM doesn’t work properly with GCS (google cloud storage). If replicasets data size more than 5Mb, uploading on GCS fails with the error `InvalidArgument: Invalid argument. status code: 400, request id: , host id: .` Backup from replicas with the data less than 5Mb works fine. Minio and AWS work fine.
