Add OidcAuthenticationListener for capturing important code flow events

[sberyozkin]

Description
There has been a request for LoginEvent be reported when the current user authenticates for the first time (or re-authenticates). The current workaround is to use SecurityIdentityAugmentor which can not detect if it is a new OIDC code flow authentication or not

Implementation ideas
We already have a new_authentication property set on RoutingContext when the code flow starts but it does not work in all the cases.
It can make sense to introduce an interface like OidcAuthenticationListener (or similarly named) which will capture not only Login but Logout, auto-reauthentication via refreshing the tokens, etc
