ARTEMIS-994 Support Netty Native Epoll on Linux
The following changes are made to support Epoll.
Refactored SharedNioEventLoopGroup into renamed SharedEventLoopGroup to be
generic (as so we can re-use for both Nio and Epoll)
Add support and toggles for Epoll in NettyAcceptor and NettyConnector (with
fall back to NIO if cannot load Epoll)
Removal from code of PartialPooledByteBufAllocator, caused bad address when
doing native, and no longer needed - see jira discussion
New Connector Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio
gracefully)
remotingThreads = same behaviour as nioRemotingThreads. Previous property is
depreated.
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool. Old property is
deprecated.
New Acceptor Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio
gracefully)
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool but for Epoll.
This closes #1093
