The server state and weight was reworked to handle "pending" values updated by checks/CLI/LUA/agent. These values are commited to be propagated to the LB stack. In further dev related to multi-thread, the commit will be handled into a sync point. Pending values are named using the prefix 'next_' Current values used by the LB stack are named 'cur_'
