The Federation Mount Table State encapsulates the mapping of file paths in the 
global namespace to a specific NN(nameservice) and local NN path.  The mount 
table is shared by all router instances and represents a unified view of the 
global namespace.   The state store API for the mount table allows the related 
records to be queried, updated and deleted.
