Bug Description

wsrep_forced_binlog_format option will define a binlog_format that will be always be effective regardless of session binlog_format setting.

This feature will likely be needed to support RSU method for online schema upgrades: https://bugs.launchpad.net/codership-mysql/+bug/887563

new variable wsrep_forced_binlog_format accepts values:
   ROW
   STATEMENT
   MIXED
   NONE

...so the same as with binlog_format + NONE, which works as resetting the forced state of binlog format interpretation.
