The main class was getting unwieldly and too general. Dividing the fields

MXS-2136: Convert 'passwd' to 'password'

The old 'passwd' parameter is now converted to the 'password' parameter

parameter detection functional while still allowing old-style
configurations to be used.

MXS-2142: Set causal_reads_timeout default to 10
...
The causal_reads_timeout default value is too long when considering the
behavioral changes that MXS-2141 introduced. With a 10 second default
value, a result is returned to the client in a reasonable amount of time.
2018-11-06 15:09:14 +02:00

MXS-2141: Retry query on master if it times out on slave
...
With causal_reads enabled, the query would return with an error if the
slave was not able to catch up to the master fast enough. By automatically
retrying the query on the master, we're guaranteed that a valid result is
always returned to the client.

Remove unnecessary sleeps from mxs812_2

The 20 second sleep was not needed. Using wait_for_monitor is better since
it makes sure the blocking of the nodes is visible.

Shorten mxs1585
...
The test description talks about putting the master into maintenance mode
but it spends most of the time putting slaves into maintenance mode. To
make the test more precise (and fast) the test can be reduced to blocking
the most often used slave and the master. The iteration count can also be
lowered from five to two to get at least two cycles of maintenance mode.

monitor is stopped during write.

MXS-2137 Remove meaningsless statistics
...
The removed statistics variables have no meaning anymore and
were not updated.
Decided to simply drop the variable from the JSON output. It
gets far too rigid if fields of objects cannot be changed without
bumping the REST-API version.

MXS-1467: Create csmon
...
Added the csmon monitor which supports both old and new ColumnStore
servers. As older server versions aren't able to express their role, the
master needs to be designated by the user. When a ColumnStore version is
released that supports the mcsSystemPrimary() function, the master can be
automatically found.
