Optimize the collectors of manager which listen to the graphs and nodes changes.

1. Remove the records of user graphs;
2. Remove the records of user value nodes;
3. Remove the records of user cnodes;
4. Add the records of users, and the API to access the users of graph, value node, and cnode;
5. Fix issue:User cnode record may point to its own graph, when combine the user(caller) and used one(callee);
6. Fix issue:User graphs never update itself after its first creation.
