From fd0ecadbb98a426ef0107d7b8299c60be84a548f Mon Sep 17 00:00:00 2001
From: Sean Busbey <busbey@cloudera.com>
Date: Thu, 8 Oct 2020 10:02:27 -0500
Subject: [PATCH] HBASE-14067 bundle ruby files for hbase shell into a jar.

* removes some cruft from the hbase-shell pom that appears to be from coping the hbase-server pom long ago
* puts the ruby scripts into the hbase-shell jar following the guide from jruby for packaging
* removes hard coding the location of the implementation scripts from our runtime
* removes hard coding the load path for the implementation from the test code (leaves hard coding the test code location)
* provides a work around for a name conflict between our shell and the ruby stdlib shell.

closes #2515
