v0.5.4 Nuget release

[MattB-msft]

What's Changed

• Interface Update - Bug fix for External Auth. by @MattB-msft in Interface Update - Bug fix for External Auth.  #169
  Fixed and issue with the client being non-castable to IOrganizationServiceAsync, Client will now cast again. (Internal Report)

• Special note:
  • IOrganizationServiceAsync has async methods without cancellation support. this is required for service mapping as the dataverse server does not natively support this feature.
  • IOrganizationServiceAsync2 has async methods WITH cancellation support.
    • This surfaces in the client as 2 forms of each async method and is currently necessary to support internal auto generation of contracts for service communication. We will work to improve this in the future.
    • Cancellation events will currently raise an OperationCancelled Exception, this can either be the topmost exception, or embedded in a DataverseException.
    • Cancellation methods are 'preferred' if you need to support cancellation in your application.

Fixed an issue with External authentication type not being properly passed though to cloned clients. Fixed #162
