> Currently, {{RemoteWasbAuthorizerImpl.getRelativeBlobSASUri()}},  {{RemoteWasbAuthorizerImpl.getContainerSASUri()}}
and {{RemoteSASKeyGeneratorImpl.authorize()}} use Kerberos interactive user's ticket cache
if the kerberos credential is not available for {{UserGroupInformation.getCurrentUser()}}
or {{UserGroupInformation.getRealUser()}}.
> It results in usage of interactive user's ticket for impersonation, whenever services
try to do File System operations as another user, which is incorrect.
