Ability to add and select multiple authentication options

[Chetan Sharma]

This request is to enabled users to choose the type of authentication on the main logon page, he should have option to select\click on desired type of authentication (RADIUS\SAML\AD) and then based on what user selects the next page can be as it is now for each one. Like by default I noticed we get option to select domain or local account to logon, similarly SAML\RADIUS should be listed and as soon as users selects SAML\RADIUS it should take user to the next page (offload the authentication to different provider),
