Web console to get real-time peer data

[BruceAko]

Feature request:

Currently peer data shown in web console is T+1. In more detail, when a user gets Peers information through a Web page, the information is queried from the database. The Peers metadata in the database is captured by a Sync Peers timer task that goes to the cluster every once in a while and stores it in the database. This results in the Peers information displayed on the web page not being up-to-date in real-time.

Use case:

The Sync Peers feature would be modified to remove the Peers information from the database and query the latest data from the cluster each time a Web page calls the interface. The queried data will be cached in Redis, so that users can fetch the Redis cache on subsequent visits, so that repeated queries don't slow things down. In the end, the synchronization process is changed from a timed process to a query-per-query process.
