Motivation: We should just add `executor()` to the `ChannelOutboundInvoker` interface and override this method in `Channel` to return `EventLoop`. Modifications: - Add `executor()` method to `ChannelOutboundInvoker` - Let `Channel` override this method and return `EventLoop`. - Adjust all usages of `eventLoop()` - Add some default implementations Result: API cleanup
