Added new artifact hbase-shaded-testing-util. It wraps a whole hbase-server
with its testing dependencies. Users should use only the following dependency
in pom:
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase-shaded-testing-util</artifactId>
<version>${hbase.version}</version>
<scope>test</scope>
</dependency>
Added hbase-shaded-testing-util-tester maven module which ensures
that hbase-shaded-testing-util works with a shaded client.
