Failing tests because of mysqldump --skip-column-statistics arg #5892
Description
The following test is currently failing on tests running MySQL 5.6:
Lines 159 to 170 in 7038788
Example:
001 Scenario: Ensure that Utils\run_mysql_command() passes through without reading full DB into memory # features/utils.feature:108
Then the return code should be 0 # features/utils.feature:161

That's because the --skip-column-statistics arg was only introduced later.
Can we remove the arg for this test?
If not, can we only add it on supported MySQL versions?
In other places such as DB_Command.php we first check the result of mysqldump --help | grep 'column-statistics' to see whether the arg is supported. Not sure how best to do that in Behat though.
