[RFE] Allow redirections to logoutRedirect URL for specific identityProvider (single sign on) only.

1. Proposed title of this feature request: 
   Allow redirections to logoutRedirect URL for specific identityProvider (single sign on) only.

1. What is the nature and description of the request?

• User logout action from OpenShift console uses logoutRedirect URL for all identityProviders, when more than 1 identityProviders are used.

• OCP has 2 identityProviders [OpenID and LDAP (Active Directory)]
• Configure logoutRedirect URL for OpenID identityProvider as explained in this doc [1] to perform single logout from SSO session as well from OCP logout.

• Login using a user authenticated against Active Directory. When this user logs out, the request is sent to logoutRedirect URL.

]

Affected Components:

• Auth 

• Web Console 

I had opened a BZ [2] for this, where I was informed that this is how API is designed and the logout redirect URL would be applicable to all the users.
