David Alber 6939e21f43 Moving config option tests to subdirectory ...

This was done by running the following.

```sh
for f in `find . -name "configs-*.rs"`; do
    topdir=`echo $f | cut -d/ -f2`;
    configname=`echo $f | cut -d/ -f3 | cut -d- -f2`;
    testname=`echo $f | cut -d/ -f3 | cut -d- -f3`;
    mkdir -p $topdir/configs/$configname;
    git mv $f $topdir/configs/$configname/$testname;
done
```
