      Description

      Current watcher implementation (in admin/bin/watcher.py) is based on direct watching of zookeeper updates via kazoo. If we are to re-implement CSS based on mysql then watcher needs to be updated to support it. Mysql does not have watch mechanism, so it has to be done via polling or using some other mechanism if synchronous notifications are needed.
