Server side caching of login locations

1. Description/background

AppframeworkService#getLoginLocations() becomes slow when the login locations are over a few hundreds. This is due to the filtering processes inherent to the method and the underlying methods like LocationService#getLoginLocations(). This ticket should address the undesired delay of AppframeworkService#getLoginLocations() by making the login locations in-memory than having to make a call to the database on every page/web request.
