Turn off geowiki monitoring

Due to taking the data repository off-line, the files were no longer
available on http://gp.wmflabs.org/ , and monitoring screamed at us.

We're restructuring the data repositories and bring them back online,
which requires monitoring changes. Afterwards, we'll turn monitoring
back on.

Move geowiki's name for research MySQL config into separate variable

This rephrasing makes follow-up commits that move files around more
readable.
