The insertion and subsequent read of the data into the master in
`generate_traffic_and_check` will now be done inside a transaction. This
keeps the behavior consistent with the `check` function that only inserts
one row.
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 slave" on server 2
- "disable" log-bin on server 3
- set multi-source replication on server 4
- take down master
- no slave should be promoted
- 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.
