DRILL-4623: Disable epoll transport by default
@jacques-n can you please review?
Note: although this patch disables epoll as default transport, deployments
that use another env file (e.g. `/etc/drill/conf/drill-env.sh`) would use
epoll. Or disabling could be hard coded?

> At higher concurrency (and/or spuriously), we hit [netty issue
> #3539|https://github.com/netty/netty/issues/3539]. This is an issue with the
> version of Netty Drill currently uses. Once Drill moves to a later version of
> Netty, epoll should be reenabled by default.
