> In order to check drill state information, the following tables are to be implemented:
> 1. Memory: a query such as
> select * from sys.drillmemory;
> should return a result set like the following:
> +------------+------------+--------------+------------+------------+
> |    drillbit    | total_sys_memory   |heap_size | direct_alloc_memory |
> +------------+------------+--------------+------------+------------+
> | node1:port1       | 24596676k         | 15200420k         | 1012372k   |
> +------------+------------+--------------+------------+------------+
> | node2:port2       | 24596676k         | 15200420k         | 2012372k   |
> +------------+------------+--------------+------------+------------+
> 2. Threads:
> For each node in a cluster, we need counts of threads of the drillbits.  A query like
this:
> select * from sys.drillbitthreads;
> should return a result set like the following:
> +------------+------------+--------------+------------+------------+
> |    drillbit    | pool_name   | total_threads | busy_threads |
> +------------+------------+--------------+------------+------------+
> | node1:port1       | pool1         | 8         | 2   |
> +------------+------------+--------------+------------+------------+
> | node2:port2       | pool2         | 10         | 5   |
> +------------+------------+--------------+------------+------------+
