Description

First, thanks for the project!

Now...access to Azure Blob Storage accounts requires an explicit update of the API version to a newer version. Documentation could be improved to mention that.

Current behavior:

• Calls to a Blob Storage account (do not confuse with a blob container inside a general purpose storage account) fail with the error
  org.jclouds.http.HttpResponseException: request: HEAD https://------.blob.core.windows.net/-----/Sample-20170711-064501930.pdf HTTP/1.1 failed with response: HTTP/1.1 400 The value for one of the HTTP headers is not in the correct format.
• Same code (based on example https://jclouds.apache.org/guides/azure-storage/) works when used in a general purpose account.

Applied fix
Debugging the code I could the whole error pointing to x-ms-version header, so fixing the issue was easy. Setting the API version with ContextBuilder.apiVersion to the newer version "2016-05-31" was enough.

Request
I think that a note on the example could be added to help with it, or else, just update the default version of the API, currently it uses "2013-8-15".
