Commit Message

Dont shade netty at distributedlog-core-shaded

Descriptions of the changes in this PR:

*Problem*

JVM crashed on linux platforms, when`distributedlog-core-shaded` (where netty `4.1.12.Final` was shaded) is used in a project where a non-shaded netty `4.1.21.Final` is used and epoll is enabled.

```
Event: 13.322 Thread 0x00007fef90013000 Exception <a 'java/lang/NoSuchMethodError': Method io.netty.channel.epoll.Native.epollWait0(IJII)I name or signature does not match>             (0x00000000e709c060) thrown at [/build/openjdk-8-8u141-b15/src/hotspot/src/share/vm/prims/jni.cpp, line 4011]
```

Because Epoll is enabled on linux platforms. However because two different netty versions bring in two different jni bindings, when the netty epoll transport tries to resolve the jni library, it hit the signature mismatch issue.

*Solution*

Dont shade netty at all. Let the application resolve which netty version to use.
