Unable to connect to Azure Storage from Pega using Microsoft Azure Storage SDK v8.6.4 for Java anymore

### Which service(blob, file, queue) does this issue concern?
azure storage

### Which version of the SDK was used? Please provide the output of `pip freeze`.
we have noticed that we couldn’t connect to Azure Blob Storage using SDK. We end up seeing “ HTTP/1.1 400 The value for one of the HTTP headers is not in the correct format” error with x-ms-version: 2013-08-15 header.
Seems like this is the default header value that SDK sets. When we changed the version to 2018-03-28, we didn’t run into any issues.

Please let us know if anything has changed recently at the Azure Storage that’s causing this issue.

### What problem was encountered?

### Have you found a mitigation/solution?

Begin with the reported Azure Blob Storage connection error and the x-ms-version: 2013-08-15 header. Verify the repository and version mismatch, since the title names the Java SDK while the issue template requests Python package data; done requires a reproducible diagnosis and clear resolution or compatibility guidance.
