Added options in TestObjectProvider to return compat versions of container runtime and data store runtime

[agarwal-navin]

This allows tests using testObjectProvider to create custom data objects and runtime factories with the current compat versions. For example, if the tests are running in version N-1, it will let tests create version N-1 objects. Currently, tests that are creating custom objects, always create the current version N and hence lose a lot of back compat coverage. See example tests that are updated to use the compat versions of objects.
