Stream blob upload OOM

[baelter]

Trying to use this now, and the az process is OOMing even with a tiny "length"

Related command

pg_basebackup -D - -X fetch --format tar --gzip --compress=3 --max-rate 2M | \
  az storage blob upload --data @- --length 1024 -c wal -n $(hostname -s)/base.tar.gz

The pg_basebackup process uses 8MB, and az is growing indefinitely until OOM killed (at 2GB on the current VM)

Extension name (the extension in question)

storage-blob-preview
