Jihun Cho a48ebb1616 netty: change default transport to Epoll if available, otherwise using Nio (#5581) ... Motivation: To support TCP_USER_TIMEOUT(proposal). Nio doesn't support TCP_USER_TIMEOUT while Epoll and KQueue supports TCP_USER_TIME. Since most users/servers are using linux based system, adding Epoll is necessary. KQueue maybe supported later, but not in this PR. To make it backward compatible for cases where channelType and eventLoop is mixed in with default and user provided object(s), we will fallback to Nio (NioSocketChannel, NioEventLoop). This ensures not breaking existing code (same as existing behavior). Users not specified both channelType and EventLoops will be affect by this Epoll change if netty-epoll is available. In later version (possibly 1.22.0), the backward compatible behavior will be removed and it will start to throw exception since this is error prone.		2019-04-15 17:53:14 -07:00
