Is your feature request related to a problem? Please describe.

The current azureblob package does not seem to allow to directly query the Instance Metadata Service to get credentials and relies on environment variables.

Describe the solution you'd like

If environment variables are not provided I would expect the azureblob to tentatively query the Instance Metadata Service to get credentials to be used to query the Azure Blob Storage service.

Describe alternatives you've considered
