When a model is copied from client, it results in multiple client model objects refer to the same server cached model. In this case, we need a reference count, only when reference count decreases to zero, we can release the server cached model. ### Why are the changes needed? Bugfix. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Unit tests. ### Was this patch authored or co-authored using generative AI tooling?
