Add a new implementation for OIDC Manager with different storage mechanism instead of HTTP session

[AnuradhaSK]

Describe the issue:
HTTP session-based OIDC processor has a limitation when the web app is deployed in more than one container.
Params such as nonce, state, and additional query params store in the session

   session.setAttribute(SSOAgentConstants.REQUEST_CONTEXT, requestContext);

and try to use them validate in the callback based on the session detail will be cause for issues if the callback doesn't come to the same container.

RequestContext requestContext = getRequestContext(request);

Enabling session affinity would be one solution, but not reliable because there could be container downtime.
Session replication is another option but the deployment will be complicated.
