Re: [keycloak-dev] Offline tokens - step 1

I've sent the PR . Right now it works like this: - ClientModel has flag "offlineTokensEnabled" . It's possible to retrieve offline tokens just if flag is enabled - Offline token is classic refresh token with 2 differences. It has type "OFFLINE" when normal refresh token has type "REFRESH" . And for offline token, the expiration value is 0, so it never expires. - Offline token is generated by auth-server when client sends "scope=offline_access" . It's supported for classic browser flow, but also for Direct Grant flow or Service account flow. - I've added OfflineClientSessionModel and OfflineUserSessionModel with CRUD methods on UserModel. So when new offline token is generated by Keycloak, some info about current UserSession and ClientSession is persisted on UserModel. This means that offline token can be used to create new access token even if "normal" UserSession and ClientSession are already invalid or logged out.
