Managed Identities for Managed Instances

[Kinetic-311]

Azure is pushing the Managed Identities for access to Storage Containers/Blobs now. Your product automatically appends a required credential, rightfully assuming a SAS token.

The new Managed Identities method, the MI is added without SQL Server knowledge. A credential is still created but while performing the backup a @credential is not needed, simply the URL.

Could you add this feature through a Parameter or other detection method?

It seems, on any managed instance version it forces the @credential to match the URL name, but in this case does not find a SAS method and the Azure MI rejects the backup. When Managed Identities is setup via Code or the Portal a @credential is not required and in this case fails.
