Previously, runtime monitor modifications could directly alter monitor fields,
which could leave the text-form parameters and reality out-of-sync. Also,
the configure-function was not called for the entire monitor-object, only the
module-implementation.
Now, all modifications go through the overridden configure-function, which calls the
base-class function. As most configuration changes are given in text-form, this
removes the need for specific setters. The only exceptions are the server add/remove
operations, which must modify the text-form serverlist.
The default ECMAScript syntax appears to be broken on CentOS 7 which
effectively prevents its use in most cases. A more reliable alternative
would be to use the bundled PCRE2 library but the basic POSIX regular
expressions seem to work.
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.
