This patch deprecates old stats and adds support for new stats. This implements the PULL design where client will enable stats on objects (i.e. interfaces, etc), register a call back function which will run once stats will be ready for enabled object and call HW::read_stats() periodically to read stats for enabled objects from VPP.
