Guava classpath conflict caused by kylin-jdbc 3.1.0 jar

The newly released kylin-jdbc 3.1.0 jar contains a shaded, non-repackaged version of the Guava library. This is causing class duplication with the original guava jar if it is also on the classpath which results in non-deterministic, runtime errors depending on which version of a certain guava class has been picked up by the class-loader from the 2 versions. Based on the runtime errors of the missing classes and methods, it seems to be a very old version, probably <=14.

Either implement a proper shading with package relocation or rely on transitive dependency, but do not shade non-repackaged versions of libraries.
