The test checks that failover works even when the master of the monitored
cluster is a slave to an external masters. The test also verifies that the
servers do not get unexpected status labels.
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.
- 1 master, 3 slaves
- stop maxscale so it does not autorejoin later on
- stop & reset slave on servers 3 & 4
- add data to server 4
- restart maxscale, check that server 3 is rejoined but not server 4
- manually set server 1 to replicate from server 4, creating a relay master
- check that servers 2 & 3 are redirected, making server 1 just a slave
- switchover master to server 1, check that it's the master
Also, moved some common functions into their own files. These functions
are used by multiple tests.
