Issuer parameter added to the GenerateAuthUri method

Description

Issuer parameter added to the GenerateAuthUri method of the Client class to accommodate the correct functioning of the Epic Hyperdrive integration

Motivation and Context

The way Epic Hyperdrive integration works it requires an Issuer parameter to be passed during the Duo authentication to the TrustedPath server and validated there. It works this way in the existing integration, which doesn't use the Universal Prompt. In our effort to migrate this integration to the Universal Prompt we need to implement this change

How Has This Been Tested?

Unit tests and the new parameter validation were added
