Comment:

 The global values are preserved after config commit. When new
 configuration request comes, old global values (if exist) are replaced
 with new values or new values are added if nothing exists in a storage.
 Each unit test now clears the configuration database by issuing the
 configuration string which sets subnets list and option list empty. It
 also sets uint32 values to defaults. This prevents affecting test result
 by configuration left by a previous test.

 The issue that has been left unresolved for now is #2469.

 Please review.
