miguelaferreira ea0dec77d9 Refactor DbUpgradeUtils
- Move database access code to new class DatabaseAccessObject.
    This was done to ease the effort of testing, since
    DbUpgradeUtils has a static API and it is harder to mock
    static things with Mockito.
  - Log exceptions even if ignored
  - Add unit tests for both DbUpgradeUtils and DatabaseAccessObject
  - DbUpgradeUtils.dropTableColumnsIfExist(...) no longer throws
CloudRuntimeException to make it consistent with the other methods in
the class
