AAD Auth Support for Managed Disks

[VikasMohandoss]

Is your feature request related to a problem? Please describe.
We are ready to start the CLI changes for supporting AAD Auth support for exporting and importing managed disks.

Describe the solution you'd like.
Currently for cli command "az disk create" and "az disk update",
add a new option "--data-access-auth-mode", and possible values are AzureActiveDirectory and None

Additional context
We are targeting public preview by the end of April and it will be good to have the CLI support by then.

@VikasMohandoss Since there are too many contents in the Swagger link in email, could you give us the specific PR link for the change, or give us the code link of Swagger code related to --data-access-auth-mode?

In addition, because the issue was created late, we will launch the release tomorrow, so it can't catch up with the release of the sprint. We plan to release it in the next sprint, is this time acceptable?
