azure blobstorage: Reset blob's content-encoding to allow check
This ensures the deposit checks in the elastic infra (using azure objstorage) is working. There is currently no way to prevent the content-encoding from being detected and stored in the blobstorage (various tryouts have been tested to no avail). That content-encoding, is then preventing the checking/reading to work (failing [2]).
Following the documentation, a workaround has been implemented to reset a posteriori the content-encoding [1].
It's not proper but, from repl experimentation, it's working which is better than the actual failure.

HttpResponseError: ('Received response with content-encoding: gzip, but failed to decode it.', error('Error -3 while decompressing data: incorrect header check'))
