doc/cephfs: separate commands into sections

Separate commands so that each command has its own subsection in the
section "FS Subvolumes" in the file doc/cephfs/fs-volumes.rst.
Previously, the list of commands for manipulating subvolumes was one
long, unbroken list and the beginning of one section could easily be
mistaken for the end of the previous section.
