periodically flush ResponseWriter when using response compression

This PR fixes API Compression when following logs by ensuring the compression writer periodically flushes (at the end of each write).

This is a commit extracted from #51508 to allow testing of flushing while feature remains disabled / in alpha.

Fixes https://github.com/kubernetes/kubernetes/issues/54205
