Failing tests because of mysqldump --skip-column-statistics arg

[swissspidy]

The following test is currently failing on tests running MySQL 5.6:

wp-cli/features/utils.feature

Lines 159 to 170 in 7038788

	# This throws a warning because of the password.
	When I try `{INVOKE_WP_CLI_WITH_PHP_ARGS--dmemory_limit=50M -ddisable_functions=ini_set} eval '\WP_CLI\Utils\run_mysql_command("/usr/bin/env mysqldump --skip-column-statistics --no-tablespaces {DB_NAME}", [ "user" => "{DB_USER}", "pass" => "{DB_PASSWORD}", "host" => "{DB_HOST}" ], null, true);'`
	Then the return code should be 0
	And STDOUT should not be empty
	And STDOUT should contain:
	"""
	CREATE TABLE
	"""
	And STDOUT should contain:
	"""
	{ONE_MB_OF_DATA}
	"""

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
        $ WP_CLI_PHP_ARGS='-dmemory_limit=50M -ddisable_functions=ini_set' wp eval '\WP_CLI\Utils\run_mysql_command("/usr/bin/env mysqldump --skip-column-statistics --no-tablespaces wp_cli_test", [ "user" => "wp_cli_test", "pass" => "password1", "host" => "127.0.0.1:3306" ], null, true);'

        exit status: 2 (RuntimeException)

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.
