The cdc_datatypes test did not use the correct connector and instead it
used a stale version of the MaxScale CDC Connector. The connector should
be treated as an external dependency and thus cloned at configuration
time.
- 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.
auto_failover=true
auto_rejoin=false
This test tests the following:
- Regular master-slave setup
- Create a table, insert some data
- Sync all slaves
- Stop a slave
- Insert some more data
- Sync remaining slaves
- Stop the master
- Expect the failover mechanism to pick a new master (server2)
- Bring up the slave
- Perform a switchover from server2 to server4
- Should fail
Currently it does fail, but only due to a timeout.
[mysqlmon] MASTER_GTID_WAIT() timed out on slave 'server4'.
There should be some check that would ensure that the failure happens
faster than that.

- Stop the master
- Expect the failover mechanism to pick a new master
- Bring up the slave
- Expect the slave to be rejoined
- The test starts with the usual setup of 1 master and 3 slaves.
- Then the master is taken down and it is checked that the failover
mechanism promotes some slave to master.
- This is continued until there is a single master left (no
slaves).
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.
The test is composed of a few parts.
1: Test that failover happens on master failure.
2: Test that a server with slave sql thread stopped is not promoted.
3: Test that a server with log_slave_updates=1 is promoted before others.
The test suite now compiles Jansson instead of letting the CDC connector
do it. This way the connector can be used as a very simple static library
with a dependency on the Jansson library.
The cdc-connector did not build on Ubuntu Trusty due to the wrong order of
linker flags. Moving the crypt and crypto linkage to be after
cdc-connector appears to fix it.

The test wasn't built as it is not a part of the test suite. The
executable should be built but it should not be added to the test suite.
Changed the management script to only add the configuration and added a
call to it at the start of the test.
The MaxCtrl test suite is now a part of the regression test suite. The
cluster tests are expected to fail as that is yet to be implemented.
Also fixed the return value of TestConnections::ssh_maxscale.
The fwf test now only tests the functionality of the rules themselves, not
the parsing. The fwf_syntax test handles the testing of the parser. The
fwf2 test was removed as it was almost identical with the original fwf
test.
The removal of a server from a service is intended to affect only new
sessions.
Added a test that checks that the connections are kept open even if the
server is removed from the service.
The test attempted to copy the generated CSV file from the MaxScale server
when in fact it was on the master server. Removed HEAVY label from the
test as it takes about 10 seconds to run.
Cherry-picked from commit f80cde2af149fda9c47d8f9131f82527b76af487.

The replication_manager is only designed for systems that have yum
installed which means it will always fail on non-RHEL/CentOS systems.
The query threads in mxs1323_stress were not checking whether the test had
ended while they were executing the queries. This caused test timeouts as
the queries can take a relatively long time.
When a backend is waiting for a response but no statement is stored for
the session, the buffer where the stored statement is copied is not
modified. This means that it needs to be initialized to a NULL value.
Added a test that checks that the behavior works as expected even with
persistent connections. A second test reproduces the crash by executing
parallel SET commands while slaves are blocked.
There is still a behavioral problem in readwritesplit. If a session
command is being executed and it fails on a slave, an error is sent to the
client. In this case it would not be necessary to close the session if the
master is still alive.
