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)
epollRemotingThreads = same behaviour as nioRemotingThreads but for Epoll.
useEpollGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool but for
Epoll.
New Acceptor Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to
nio gracefully)
useEpollGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool but for
Epoll.

ARTEMIS-994 Support Netty Native Epoll on Linux
Cleaner Epoll available check, and also fix for bad address caused by
PartialPooledByteBufAllocator
Remove usage of PartialPooledByteBufAllocator as per JIRA discussion, its
use since 2.0.0 is no longer needed. mvn clean install ran fine with all tests
passing.
Clean up code a little, around handling failback if epoll isnt available.
