Adding the QueryExecutor implementation

[amarathavale]

Changes included in this PR

1. Added the QueryExecutor class that facilitates sql query, using the SDK's queryItems method. This implementation is a copy-paste of what we are using.
2. Added the query interface method to Accessor. The QueryExecutor/query mechanism has not been integrated into the CTL workload yet (to limit the number of files changed in this request)
3. Refactored the resource management after the back-and-forth on what should be managed by the test and handled by the CTL workload. For local testing, the database needs to be created/managed by the test itself. Hence, added the Database management part of the resource setup.
4. Subsequently, removed the -manageResource flag from the shell script used by the Docker container.
