update azure core lib
Azure Storage implementation throws 503 errors if CosmosDB receives too many request. It usually throws RequestRateTooLargeException and http result code 503 . This creates service availability SLO drop.
MR updates azure core lib to change response code to 429 instead of 503 in case of cosmos db RequestRateTooLargeException.
