is it possible to shade the common dependency of the hitsdb-client?

比如项目中如果引用了某个库且该库依赖于 org.apache.httpcomponents.httpcore-4.4.11，但是当前的hitsdb-client 依赖于 4.4.6

这种情况下 在创建客户端时就会报错：

Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE

    at org.apache.http.impl.nio.codecs.DefaultHttpRequestWriterFactory.<init>(DefaultHttpRequestWriterFactory.java:57)

虽然可以通过 exclusion 来解决这样的问题，但是用户体验是比较差的。最好是能在这种情况下，不要报错。这个 Issue 就希望讨论下是不是可以将 TSDB SDK 的依赖进行 shaded ，以便于跟用户其它部分的依赖相隔离。
