add custom 'afterTokenVerified' function (similar to beforeCreateToken) after succesfull verification in volos-oauth

[borisirota]

Hi,

Add user defined function to the token verification flow that receives the verification result and the callback. This function will be able to return customized data that will be attached to the token attribute instead of the current token's verification data.
More custom way is to pass the req object to this function in order to be able to attach user's defined attributes to the req object but it requires some fundamental changes in the implementation.

Adding this kind of operation will make the authentication process more customizable from user perspective and this support will be similar to passport's serialize\deserialize methods (e.g. in beforeCreateToken we can store user's id in attributes and in afterTokenVerified it will be possible to get the user from the database and attach to the request).

To support this it requires:

1. Be able to add afterTokenVerified to x-a127-services:oauth2:options in swagger.yaml.
2. Duplicate this check only with afterTokenVerified attribute.
3. Duplicate this only with afterTokenVerified attribute.
4. Call the method instead of this callback
5. If no function supplied, the current behavior is the default.

Thanks,
Boris

This sounds like a great addition. Do you want to submit a PR? Otherwise, I'll look into this (hopefully) soon.
