Documentation Update

"The recommended boot diagnostics experience is to use a managed storage account, as it yields significant performance improvements in the time to create an Azure VM." Source: Azure boot diagnostics

The Azure RM Provider already has support (observable in expandBootDiagnostics func) to utilize Managed Storage Account for VM Boot Diagnostics; however, the azurerm provider object documentation doesn't reflect that this is possible.

This is a documentation only issue / pull request to add this to the documentation.
