Allow specifying the log directory

I know this repo is in the attic because it is deprecated. We have a task in the backlog to move to the new elasticsearch module, and upgrade elasticsearch. However, we have a more pressing need to move the log directory off of the root partition as it has been verbose and filled the root partition. We are also investigating the root cause of the verbosity, but moving the log directory should mitigate some of the issues we have seen.
