Move a entityGroup.  Optionally specify target entityGroupserver else we choose one
at random.  NOTE: You pass the encoded entityGroup name, not the entityGroup name so
this command is a little different to the others.  The encoded entityGroup name
is the hash suffix on entityGroup names: e.g. if the entityGroup name were
TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396. then
the encoded entityGroup name portion is 527db22f95c8a9e0116f0cc13c680396
A server name is its host, port plus startcode. For example:
host187.example.com,60020,1289493121758
Examples:

  hbase> move 'ENCODED_entityGroupNAME'
  hbase> move 'ENCODED_entityGroupNAME', 'SERVER_NAME'
EOF
      end

      def command(encoded_entityGroup_name, server_name = nil)

          admin.move(encoded_entityGroup_name, server_name)
        end
      end
