Description

There are some places in the code where we use hard-coded strings instead of the equivalent DFSConfigKeys define, and a couple places where the default is defined multiple places (once in DFSConfigKeys and once elsewhere, though both have the same value). This is error-prone, and also a pain in that it prevents eclipse from easily showing you all the places where a particular config option is used. Let's replace all the uses of the hard-coded option strings with uses of the corresponding variables in DFSConfigKeys.
