For example:

swss-common: Stabilize the ConsumerTable

* Fixing autoreconf
* Fixing unit-tests by adding checkers and initialize the DB before start
* Adding the ability to select from multiple channels
* Health-Monitor - The idea of the patch is that if something went wrong with the notification channel,
  we will have the option to know about it (Query the LLEN table length).
