Description: This extends setKeepAlive() for net.Socket based on the newer UV uv_tcp_keepalive_ex extension with allows setting these optional arguments for the probe interval and probe count, effectively closing the gap on setsockopt(2) compatibility. This does not extend this option to other constructors accepting keepalive options currently although that could also be added as well. Both new values default to the previous libuv behaviour (1000 ms interval, 10 probes), so existing calls are unaffected.
