Inspect MarFS configuration in use by FUSE #184

We discussed a way to have a /marfs/proc file to see what MarFS configuration is in the FUSE daemon's memory. FUSE would create this when it runs and it goes away when FUSE goes down. This is similar to the hidden files that PLFS maintained.

Work on implementing this capability, but if this proves more difficult than envisioned, it can wait until later.

Possible solutions:

We could hash the config file and check the hash in FUSE to make sure you are running the newest config.
Check mtime of config file to ensure we have the newest version.
Consider hidden .proc file with the information
admin tools (that do not exist yet) for adding and creating namespaces could also be used to manage FUSE daemon when you modify config
