List the quota settings added to the system.
You can filter the result based on USER, TABLE, or NAMESPACE.

For example:

    hbase> list_quotas
    hbase> list_quotas USER => 'bob.*'
    hbase> list_quotas USER => 'bob.*', TABLE => 't1'
    hbase> list_quotas USER => 'bob.*', NAMESPACE => 'ns.*'
    hbase> list_quotas TABLE => 'myTable'
    hbase> list_quotas NAMESPACE => 'ns.*'
EOF

        end

        formatter.footer(now, count)
