[tool] Add output format for 'table list' CLI tool.

The output format could be one of 'json', 'json_compact' or 'pretty'.
The default format is 'pretty'. With this patch, we can get the table
info more convenient for automatic processing in case of large-scale cluster.

The command with 'list_table_output' looks like:
 `kudu table list <master_addresses> [-tables=<tables>] [-list_tablets] [-show_table_info] [-negotiation_timeout_ms=<ms>] [-timeout_ms=<ms>] [-list_table_output_format=<pretty|json|json_compact>]`

The 'pretty' format output looks like:
`
TestTableListPartition num_tablets:4 num_replicas:1 live_row_count:0
  T 390c65375d13434393d7152690e80082 : HASH (key_hash0) PARTITION 0, RANGE (key_range) PARTITION 0 <= VALUES < 1
    L 7b12b3459e2943a981d22aa70b915637 tserver1:7050
  T 7cff0635ec7446f883b6b2ed9c4bf7be : HASH (key_hash0) PARTITION 0, RANGE (key_range) PARTITION 2 <= VALUES < 3

The 'json' format output looks like:
`
