Description

Currently, our hbase-shell command line argument parser is custom-rolled. It would be awesome to instead use Ruby's GetoptLong or OptionParser.

• https://ruby-doc.org/stdlib-2.3.0/libdoc/getoptlong/rdoc/GetoptLong.html
• https://ruby-doc.org/stdlib-2.3.0/libdoc/optparse/rdoc/OptionParser.html

There is a long-standing FIXME comment in bin/hirb.rb to address this: https://github.com/apache/hbase/blob/975cdf7b88f001aa51d83395c663892f3b5ffbdb/bin/hirb.rb#L50
