MXS-3337: Select lowercase variable names

Browse Source 
The current code assumes that the variable names are in lowercase. This
fixes the galera monitoring that was broken by commit
43068d20b43a34d5f3b4b4db0fcce701b3cd7cad. In addition, lowercase names
also helps when comparisons are done with std::string.
