- add initial support for creating client connections on the MDS,
  configs will need to be recreated. (The version has been updated
  to force this.)

- create a new config object, "filesystem" which represents a
  specific filesystem.  In the zero-config future, the MDS will be
  need to be aware of what filesystems it "owns," so this is perhaps one
  tiny step in that direction.
