mdbci call can heppen before maxsales object creation and segfault hapens
To avoid it call of ssh for 'maxscale --version-full' is moved to the end
of Testconnections constructor
Previously Maxscale version check was in the 'check_backend', but this was
removed from the tests execution process. Now 'maxscale --version-full'
is added to nodes creation function - to call_mdbci()
Since UNIONs that would allow a column to be masked are
rejected, there is no need to check that masking is performed
since we will never get that far.
Basic tests can be executed with 15 machines Master/slave backend. Tests have label BIG_REPL_BACKEND Default template modified to support big backend. Tests temporaraly labeled as UNSTABLE to prevent their execution nightly
For big test maxscale.cnf is automatically generated for any number of nodes
The test seems to fail from time to time due to the monitor not picking up
the master state fast enough. To prevent this, the test needs to wait for
at least one monitor interval.

If case of MDBCI_VM_PATH variable does not have trailing slash full names of _network_config
and _lables files are defined in the wrong way: MDBCI_VM_PATH is interpreted as a part of file name
instead of direcoty name
In case when nodes/servers/replication/etc in backend are broken test can not
get proper version information and exits without doing anything.
To avoid it, test first checks backend, call fix_replication() if needed
and only after that tris to check if backend version is ok for this test
The checking of MariaDB and Galera nodes is now done asynchronously while
the MaxScale check is done which leads to faster testing. Rough
measurements show that doing all the work in parallel reduces test startup
time by two seconds. Most of the time appears to still be in the MaxScale
startup which takes on average three to four seconds per test.
The numeric values of the labels aren't of value when inspecting test
results. For this reason, it makes sense to put them behind the verbose
flag to make test framework debugging happen purpose.
maxscale-system-test changed in order to control test environment by itself.
Every test checks which machines are running, compare with list of needed machines
and start new VMs is they are missing in the running machines list.
Tests are executiong MDBCI commands, MDBCI executable should be in the PATH
