The *_command functions in librados and libcephfs document the use
of specific free functions for data allocated. These functions are
currently just wrappers around C's free() function. However, to be
more strictly compliant this change adds a free-function callback
to the CommandOutput type and the specific free functions are now
used outside the unit tests.

Similar to the functions in the rados pkg, cephfs package has a function
MdsCommand that is mostly boilerplate that to set up the C function's
arguments. Replace it with the types from the new cutil internal
package.

Start organizing some of the cephfs functionality into functions grouped
by files by moving the MDS command functions into a new file. Move the
tests dedicated to those functions into a new matching file too.
