Fix PS-1827 (LP #1736921: Inconsistent and unsafe FLUSH behavior in terms of replication) (5.6)

Question

https://jira.percona.com/browse/PS-1827

Introduced new global boolean system variable 'binlog_skip_flush_commands'. When set to 'ON', all 'FLUSH ' statements are not written to the binary log.

Added 'binlog.bug88720' MTR test case which checks if various 'FLUSH ' statements change 'gtid_executed' when 'binlog_skip_flush_commands' is set to 'ON'.

Added 'sys_vars.binlog_skip_flush_commands_basic' MTR test case which checks basic global boolean system variable functionality.

Re-recorded 'main.mysqld--help-notwin' MTR test case because of the new variable added.
