Integration with status reporter in wsrep-lib. Status reporter reports changes in wsrep state and logged errors/ warnings to a json file which then can be read and interpreted by an external monitoring tool. Rationale: until the server is fully initialized it is unaccessible by client and the only source of information is an error log which is not machine-friendly. Since wsrep node can spend a very long time in initialization phase (state transfer), it may be a very long time that automatic tools can't easily monitor its liveness and progression. New variable: wsrep_status_file specifies the output file name. If not set, no file is created and no reporting is done. Reviewed-by: Jan Lindström <jan.lindstrom@mariadb.com>
* 'wsrep' suite is designated for tests which do not require a multi-node galera cluster. * As these tests are specific to wsrep-related functionalities, they must skip on server built without wsrep patch (vanilla).
