perf: fix 1ms per async CopyAPI (regression since 42.2.5) (#1314)
The problem is SSL sockets use buffers for input, and `stream#available()` might easily return 0 even though the data
isavailable in the downstream socket. The only viable WA is to perform `read` calls, however it might impact
performance(e.g. for async copy operations). The resolution is to throttle read calls for copy api, and keep 1ms reads
forreplication api.
fixes #1312
