The tests now reset the replication state using queries and switchover instead of
calling fix_replication(). The results are checked so these tests now test
switchover as well.
Also, reduce printing when verbose is on for any test using the get_output()-function
in fail_switch_rejoin_common.cpp.
The same test now has two versions. In the automatic version failover
begins automatically. In the manual version failover is started with
maxadmin. The tests are otherwise identical.
