- fixed wrong plugin stats structure handling:

 - removed plugin_global_stats variable and unnecessary "global scope" functions;
       - added pointer on chassis_plugin_config that points to chassis_plugin_local_stats_t of chassis_plugin structure;
       - now we can access each plugin local stats through chassis_plugin_config;

- code refactoring on setting and getting statistic;
- fixed interface incorrect behaviour on some cases;
