WIP [tools] add --row_count_only and --report_scanner_stats flags
This patch updates `kudu table scan` and `kudu perf table_scan` CLI
tools to introduce two new flags:
* --row_count_only
* --report_scanner_stats
I also added a few generic test scenarios for the new functionality.
The motivation for this patch the necessity to:
* have an explicit option to run something similar to
SELECT COUNT(1) FROM <table_name> when using `kudu perf scan_table`
and `kudu table scan` CLI tools
* report on the scanner metrics while running a query like
SELECT COUNT(1) FROM <table_name>
WIP:
* make sure the newly added tests pass
