Cannot generate SAS URI from BlobContainerClient created through BlobServiceClient.GetBlobContainerClient

[mikamins]

Describe the bug
A SAS URI cannot be generated from a BlobContainerClient obtained through BlobServiceClient.GetBlobContainerClient.

Expected behavior
If a BlobServiceClient is created from an account key connection string, I expect a BlobContainerClient obtained through BlobServiceClient.GetBlobContainerClient to be able to generate a SAS URI.

That is, I expect the following test to pass:

    [TestMethod]
    public void ContainerClientCanGenerateSasUri()
    {
        var connectionString = "UseDevelopmentStorage=true;";
        var serviceClient = new BlobServiceClient(connectionString);
        var containerClient = serviceClient.GetBlobContainerClient("test");

         // passes as expected
        Assert.IsTrue(serviceClient.CanGenerateAccountSasUri);

         // fails unexpectedly
        Assert.IsTrue(containerClient.CanGenerateSasUri);
    }

Actual behavior (include Exception or Stack Trace)
In the above example, containerClient.CanGenerateSasUri returns false.

To Reproduce

1. Create a BlobServiceClient from an account key connection string
2. Call GetBlobContainerClient on the service client
3. CanGenerateSasUri returns false since the StorageSharedKeyCredential isn't passed to the container

Environment:

• Name and version of the Library package used: Azure.Storage.Blobs 12.7.0
• Hosting platform or OS and .NET runtime version: Windows 10 .NET Framework 4.7.2
• IDE and version : Visual Studio 16.3

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @xgithubtriage.
