Build filesystem monitor

[bourque]

We should build a script that will monitor and gather statistics about the filesystem. We should be able to easily answer questions like:

• How many files are there in total?
• How much disk space is used by all of the files?
• How many <some_filetype> files are there?
• Other questions I can't think of right now.

I envision the script will create a series of bokeh or matplotlib plots that show these statistics over time. These plots can eventually be hosted on our web application. Currently our filesystem is just some static test filesystem, so the plots will be quite boring for now. But this will become more useful after launch.

This script will become one of the monitors that get run by cron once a day on our virtual machine. Output products should be directed to a specific directory (to be determined).

@cracraft Can I assign this one to you?

Sure, I'll start looking into it.
