Make consent valid for login session in OIDC

[DMHP]

Description:
Currently when we provide consent as 'approve' from the dialog box it maintains the consent per request not for sessions. This limitation impacts OIDC session management as well. Because, to get session management to work, either consent should be skipped or should be approved always by the user. So we should introduce a configuration to support user consents per login sessions as well.

Steps to reproduce:

1. Configure IS server with playground app
2. Send an authorization request using authorization code grant type
3. For the consent provide 'approve' from the dialogue box.
4. In the same user session again invoke authorization EP using the same grant.
5. It will ask for the consent again.
   We need to have a way to configure consent per user login session.
