Need to implement Db_SetInitDone, just checking session_state_ in CqlIfImpl to be CONNECTED is not enough.

2. contrail-query-engine core

contrail-query-engine can come up before contrail-collector and hence it can do a Db_GetRow() of not created SYSTEM_OBJECT_TABLE and hence the table meta will be NULL. This is a valid scenario which should be handled by failing the Db_GetRow without the assert.
