Swagger update required for user assigned MSI

[navdixit]

We are using Fluent SDK Microsoft.Azure.Management.AppService.Fluent (ref: https://github.com/Azure/azure-libraries-for-net) for creating Azure functions. We are planning to use “user assigned” MSI for functions apps. When we followed the documentation, couldn’t find an option to assign “user assigned MSI” to a functions app using Fluent library.
To have this feature done in fluent sdk, swagger update is needed.

James Christianson should be able to help on this issue.
