EpollEventLoopGroup class is marked as final and cannot be inherited

[heixiaoma]

I currently have a requirement to wrap the Executor. While it's possible to inherit and override NioEventLoopGroup, the same is not possible for EpollEventLoopGroup. Additionally, the constructor for EpollEventLoop is not public. I'm wondering if there are any plans to make these accessible in the future, as it would greatly facilitate flexible control
