printf -> fmt::print in files inc warm_storage/integration/ws_client/…

…tests/CppClientTests.cpp

Summary:
One of our [C++ 2024 Modern Code Better Engineering Goals](https://fb.workplace.com/groups/fbcode.fyi/posts/6837863056249437) is to reduce or eliminate the use of printf in our codebase, replacing it with safer and more performant alternatives.

This diff replaces `printf` with its preferred alternative: `fmt::print`.

This diff was auto-generated by fbcode/scripts/rbarnes/printf_upgrader.py, please reach out to r-barnes if you see problems.
